Be My Boyfriend tells a story of a beautiful and popular girl named Oh Ji-na.
Ji-na is a second-grade high school student who became an idol trainee at a big agency after going through very tight competition.
Together with her two friends, a girl named Seong Han-na,
an idol trainee, and Joo Min-ji, a girl from a rich family,
Ji-na becomes the most popular and prestigious student at her school.
Meanwhile, on the other hand,
a first-year student named Lee Seung-min can only look at Ji-na and her two friends from a distance.
Seung-min is an ordinary young man whose life is ordinary.
He has a big crush on Ji-na, nicknamed 'the goddess' because of her beauty.
Seung-min's friend, Ba-ul, always teases Seung-min because he dreams of dating Ji-na.
Ba-ul thinks that Seung-min hopes too high because Oh Ji-na is like living in another world that he cannot achieve.
However, Seung-min never gets discouraged and tells Ba-ul that everyone has the right to like anyone in this world.
One day, when Ji-na and her two friends were about to enter their class,
a handsome young man named Hyung-tak approached them.
He is one of the popular students and the best baseball player in the school.
Hyung-tak and Ji-na are couple. But it seems they are having problems and are involved in a serious debate.
Ji-na turns out to be annoyed that Hyung-tak often ignores her and always uses baseball as an excuse.
Ji-na tries to understand Hyung-tak, but she thinks that he has gone too far, and she doesn't want to be disappointed again.
Therefore, she decided to end their relationship right away.
Hearing this, Hyung-tak then feels annoyed and refuses to end their romantic relationship.
He then demands an explanation as to why she chose to end their relationship for a trivial reason.
However, Ji-na, fed up, tells Hyung-tak that she already has another boyfriend who loves and cares for her more.
She is immediately confused when he asks about her new boyfriend.
Being pressed by Hyung-tak, Ji-na randomly chooses one of the students whose face is
plastered on the wall magazine at school, and she points to a photo of Lee Seung-min, a first-year
student who is a member of the broadcasting club.
Hyung-tak then asks Ji-na to introduce her new
boyfriend to himself because then he can only accept that their love affair is really over.
Ji-na and her two friends immediately look for Seung-min's whereabouts before Min-ji finally meets Ba-ul,
who thinks Seung-min has made a big mistake on Ji-na and her friends.
Ba-ul rushes to see Seung-min and tells him that Ji-na is waiting for him on the school roof.
When Seung-min and Ji-na finally meet, she firmly asks him to be her boyfriend.
The scene then switches to the past, to be precise, a few months before when Seung-min
first met Ji-na in the broadcasting room. At that time, Ji-na was singing a song and her voice sounded very sweet.
Seung-min fell in love with her right away.
Therefore, Seung-min had no idea that Ji-na was now standing before him and asking him to date.
Seung-min is curious and asks if Ji-na asked him out because she likes him.
She replies that she just met him today, so she can't possibly like him.
She then explains that they will be dating for a while,
just like the protagonist's contractual relationship in a romantic drama. Hearing this,
Seung-min immediately rejects Ji-na's offer to date her because he doesn't want to have a
romantic relationship based on dishonesty. Getting rejected by Seung-min seems to make Ji-na nervous
about it because, in all her life, no one has ever rejected her, and she feels humiliated. The next
day, Ji-na goes back to Seung-min and explains why she chose him as her new boyfriend. Ji-na confirms
that she has prepared a contract so that neither party feels disadvantaged in the relationship.
Seung-min seems to consider Ji-na's offer and puts some conditions on her so that they really look
like a real couple. Ji-na doesn't mind Seung-min's terms because she thinks their relationship is
only temporary. Hearing this, Seung-min hesitated for a moment before signing the contract.
Ba-ul, who knows that Seung-min and Ji-na have a contractual relationship, then tells Seung-min
not to waste the opportunity to date Ji-na even if it's only temporary. Seung-min actually wants
to take the opportunity, especially since he has fallen in love with her at first sight.
However, Seung-min remembers his late mother's advice to ask him to live an honest life.
Ba-ul tries to convince Seung-min by saying that he could have used the contract to make Ji-na
really fall in love with him, and they became a real couple. After being convinced by his best
friend, Seung-min finally signs the contract and bravely confesses in front of everyone,
including Hyung-tak, that he is Oh Ji-na's boyfriend. After that, Seung-min asks his
father for advice on how to win over a woman. The next day, Seung-min buys food for Ji-na.
Even though it's simple, it turns out to be enough to impress her. To avoid Hyung-tak, Ji-na invites
Seung-min to come home from school together. The two of them then stopped at a place and made an
approach to understand each other better so that their relationship was not suspected.
Ji-na then tells Seung-min that she'll be practicing in the studio, and it might take
a while. However, Seung-min says that he will still wait for her so he can take her home. While
practicing, Ji-na meets Han-na, who questions Ji-na's attitude towards Seung-min and says
that he is not worthy of her because he is just an ordinary person. Ji-na looks surprised that
Seung-min actually waited for hours to take her home. Ji-na almost gets hit by a car because of a
broken traffic light. Seung-min says he will call the residential headquarters and report the matter
because a broken traffic light is a serious hazard to road users. But Ji-na chooses not to worry too
much about it. She then asks for Seung-min's phone number if something goes wrong. After entering his
number on Ji-na's cell phone, Seung-min bids her goodnight before they part. At the weekend, Ji-na,
who was hanging out with Min-Ji and Han-na, then contacted Seung-min and asked him to join them.
Since Seung-min is with Ba-ul, they both end up there. Unlike Min-ji and Ji-na, who seemed
comfortable with Seung-min and Ba-ul's presence, Han-na didn't like them, so she decided to leave.
Seung-min then invites them to his regular internet cafe, which serves a delicious food menu.
Even though the dish looked nothing special, it was so delicious that it impressed them.
While they're playing the game, Ji-na surprisingly plays the game pretty well
and beats them all. When Seung-min was about to go home, he put his jacket on Ji-na. Although,
in reality, it is not as romantic as expected, he does it because he really cares for her.
The next day, Seung-min accidentally runs into Hyung-tak, who doesn't seem to like him.
When Hyung-tak and his friends were about to intimidate Seung-min, suddenly, Ji-na
came to return Seung-min's jacket. She then tells Hyung-tak not to bother her boyfriend, or he will
come face-to-face with her. Because Hyung-tak is constantly badmouthing Seung-min in front of her,
Ji-na is irritated and grabs Seung-min's neck and kisses him in front of Hyung-tak and his friends.
The incident makes Seung-min's heart pound with shame, while Hyung-tak is
annoyed and then rushes to leave them. However, instead of feeling happy because of the kiss,
Seung-min feels disappointed in Ji-na because she only uses him to make Hyung-tak jealous. Despite
being annoyed, Hyung-tak decides not to give up and is determined to get Ji-na's love back.
He tries to impress Ji-na with his athletic body. But it turns out that she is not impressed by what
Hyung-tak is doing. Ji-na then invites Min-ji and Ba-ul to lunch and asks Ba-ul to invite Seung-min.
But Seung-min refuses to have lunch with Ji-na because he still feels disappointed in her.
When Seung-min was about to return to class, he accidentally crossed paths with Han-na,
who looked very pale because she was on a strict diet to maintain her ideal weight
according to the agency's demands that sheltered her. Seung-min tries to help Han-na,
but she refuses because she thinks he just wants to make fun of her. Seung-min denies this saying
that everyone deserves to fight for something they want to get in life. Meanwhile, Ji-na
finally finds out that Seung-min actually likes her before entering a contractual relationship.
Ba-ul tells that Seung-min is a person who values ??sincerity, so he advises Ji-na to do everything
with sincerity, even if it's a contractual relationship with Seung-min. Instead of ignoring
Han-na, Seung-min gives her a can of isotonic drink, so she doesn't become dehydrated. Han-na
then feels surprised when Seung-min calls her cool for fighting for something important to her. She
gets such praise for the first time as everyone sneers at her for trying so hard to keep her
weight off. Ji-na and Seung-min finally face each other, and she then asks him when he likes her.
Seung-min reveals that he first saw Ji-na while singing in the broadcasting room, and that's when
he immediately had a big crush on her. She then apologizes to him for what happened between them.
Seeing Ji-na, who looks really sorry for her actions, Seung-min finally forgives her.
That night, when Ji-na and Han-na had training, the agency told Han-na that
her abilities were still like amateurs, even though she had practiced for years. Meanwhile,
Ji-na received praise because she has amazing abilities despite being the last trainee to enter
the agency, surpassing her seniors. Time flies. Ji-na and Seung-min don't realize that they will
celebrate their anniversary. Seung-min gives Ji-na a bag as a gift. Even though it's not a luxury bag
and is a couple item, she looks happy when she gets a gift from him because it turns out that he
hasn't forgotten their anniversary. Seeing this, Hyung-tak remembers the past when he was still
dating Ji-na, where at that time, she faithfully waited for him to practice baseball and give gifts
to celebrate their anniversary. However, Hyung-tak forgets about it and makes Ji-na disappointed.
Hyung-tak then meets Han-na and is seen to be planning something with her related to Ji-na.
After school, Ji-na is forced to cancel her dinner with Seung-min due to urgent business. After that,
Han-na meets Seung-min and invites him to attend a fan sign event for a singer they both like.
Without the slightest suspicion, Seung-min accepts Han-na's invitation. That night, after attending a
fan sign event with Han-na, Seung-min accidentally met Ji-na, who was with Hyung-tak. Before leaving
school, Ji-na gets word from Han-na about someone from the agency who wants to meet her in person.
When Ji-na comes to the place, it turns out that the one there is Hyung-tak, who regrets
his actions and wants to make up with her again. Hyung-tak then gives some of the anniversary gifts
they've missed. Ji-na thanks and then explains that at that time, what she wanted the most was
a caring, and he was always by her side, not the fancy gifts that he could buy for her.
Seeing Ji-na with Hyung-tak, Seung-min feels annoyed that he had been lied to,
and Ji-na feels that she has been tricked by Hyung-tak and Han-na.
Seung-min then rushes off when Ji-na then chases him and asks why he went with Han-na.
Because Seung-min doesn't respond, Ji-na finally leaves feeling disappointed.
On the way home, Ji-na accidentally bumps into a bespectacled young man who quietly follows her.
Knowing that Ji-na went home alone, Hyung-tak then scolded Seung-min for letting her alone.
He then informs that recently Ji-na was being stalked by someone who left a mysterious message
in her locker and took pictures secretly. Hyung-tak says that Seung-min is not a
good boyfriend because he didn't realize this happened to Ji-na. Meanwhile, on the other hand,
Ji-na tries to contact Hyung-tak because it turns out that the bespectacled young man who bumped
into her was a member of the school's baseball team and one of Hyung-tak s friends. But then,
the young man snatches Ji-na's cell phone and explains that he has liked her for a long time.
Seeing Ji-na kissing Seung-min in front of him made him feel irritated and disgusted because
she prefers Seung-min, a nobody. Seung-min and Hyung-tak split up to find Ji-na before Seung-min
finally finds Ji-na, who is threatened by the young man. Hyung-tak, who had just arrived there,
jumps into action and manages to knock the young man and hand him over to the police before the
school disciplinary committee takes action for his unlawful act. Before leaving, Hyung-tak tells
Seung-min to always take care of Ji-na if he wants to stay by her side. Seung-min then apologizes
to Ji-na for ignoring her. She forgives him and then invites him to spend the night at her house.
The two of them then celebrated their anniversary by having a meal together.
Seung-min, who was very sleepy, fell asleep leaning on Ji-na's shoulder, and they slept
together. One day, Ji-na, Seung-min, and their friends, including Han-na and Hyung-tak,
decide to vacation in Min-ji's unoccupied mansions. They do a lot of fun things together.
Seeing the closeness of Seung-min and Han-na, Ji-na then felt jealous but was reluctant to
admit it in front of Seung-min. That night, when they are alone, Ji-na sings a song for Seung-min.
The very romantic atmosphere almost made them kiss. However, unbeknownst to Ji-na and Seung-min,
Han-na watches the two of them from a distance and feels a little jealous because she seems to have
started to like Seung-min. Annoyed at constantly feeling defeated by Ji-na, Han-na becomes more
irritable and triggers an argument with her. When Ji-na and Han-na were practicing in the studio,
the agency came and informed them that the agency company was experiencing financial problems.
So they would charge training fees to trainees, especially trainees who did
not show good development like Han-na. Hearing this, Ji-na tries to defend Han-na and says it
is against the law because it is not written in the contract. Instead of agreeing with Ji-na,
who has defended her, Han-na prefers to give some money to maintain her position.
Ji-na finally chose to leave Han-na and her agency because she was disappointed in them. Ji-na then
goes to Seung-min and tells him everything. He said that she had acted properly because the
agency had committed a violation that harmed the trainees. Seung-min then shows the video footage
showing Ji-na singing. He then suggests she upload the video on Youtube so that many people know her
potential and her opportunities to debut will be more wide open. One day, Ji-na meets her older
sister and reveals her contractual relationship with Seung-min. Ji-na says she has fallen in love
with him and plans to confess her love after their contract ends. On the other hand, the agency asked
Han-na to persuade Ji-na to return. But Han-na says that she is no longer friends with her.
The next day, Ji-na tells Seung-min that she has uploaded the video on Youtube, and he is surprised
because her video has been watched a hundred thousand times. While studying together, Ba-ul
and Min-ji stumbled across Seung-min and Ji-na's contract agreement. Han-na, knowing this, seems to
be wondering in her heart. Han-na finds out that Ji-na has uploaded the video on Youtube and gets a
lot of praise. Han-na, who is annoyed that Ji-na is now the center of attention, then snaps at
Hyung-tak in annoyance that he asks where Ji-na is as if implying that everyone only cares about her.
Han-na then goes to Seung-min and asks him to be her boyfriend after his contract with Ji-na ends.
Seung-min does not respond to anything, and Ji-na, who knows this, immediately invites him to leave.
Meanwhile, Ba-ul looks very surprised when he finds out the news has gone viral on social media,
where the contract agreement between Ji-na and Seung-min is widespread. All students
corner Ji-na in this and think she just wants to take advantage of Seung-min and play with him.
Ji-na gets a lot of criticism and hates speech from everyone. Ba-ul then goes to Seung-min
and admits that the contract was spread because of his carelessness.
After that, Han-na lied to Seung-min by saying that Ji-na didn't want to see him. Even though
Ji-na really hopes for Seung-min's presence by her side to face these problems together.
With the help of Min-ji and Ba-ul, Ji-na finally finds the person who spread the contract first and
is none other than Han-na. When Ji-na confronted Han-na about it, she didn't deny it and told Ji-na
that she did it on purpose so that Ji-na felt the pain she had been feeling for always losing
to her. Han-na apparently never considered Ji-na a friend because she always felt sick whenever Ji-na
grabbed everyone's attention. Han-na then feels jealous of Ji-na, who is beautiful,
is good at singing, has a loyal and kind boyfriend, and is liked by everyone. Ji-na
then says that she got it all by going through an uphill battle. She tries desperately to achieve
all her wishes and invites Han-na to come true together for their dreams. However, Han-na refuses
because she thinks that Ji-na will always win, while she is always the loser and is humiliated.
On the other hand, Hyung-tak knows that Ji-na is in trouble, and he is willing to leave the
game to help her. Likewise, Seung-min announced to everyone at school that he did have a contractual
relationship with Ji-na, but they lived it happily and without the slightest coercion.
Seung-min says that with the contract, he has the opportunity to get to know Ji-na more closely
and become truly in love with her. He then asks everyone to support his relationship with Ji-na
and no longer corners her because he did the contractual relationship without any coercion.
Everyone is surprised by Seung-min's bravery and praises him. In the end,
Seung-min had to accept punishment for using school facilities for his personal purposes.
Meanwhile, Ji-na is surprised and amazed that Seung-min has posted notes mentioning
his support for her in various places. Hyung-tak arrives late when all the problems are resolved.
He doesn't regret his actions despite receiving punishment
and realizes that Ji-na has now completely turned away from him and only thinks about Seung-min.
After the incident, Ji-na tries to repair her relationship with Han-na because, for her,
Han-na will always be her friend. Seeing Ji-na's sincerity, Han-na then puts forward a condition
that she will be friends with her if Ji-na decides to end her relationship with Seung-min.
Ji-na is faced with the difficult choice of choosing her friend or boyfriend. On the last
day of the contract, Ji-na invites Seung-min to skip school, and they go to various places
and do fun things as a happy couple. When their contract officially ended right at midnight, Ji-na
decided to end her relationship with Seung-min because it turned out that she preferred Han-na.
Hearing that, Seung-min didn't even think that Ji-na chose to end their relationship
after they had been through together. It doesn't stop there, Ji-na is even cold to Seung-min and
always avoids him. However, when Hyung-tak asks Ji-na about her relationship with Seung-min,
she says that she has ended her relationship with him with tears in her eyes.
Seeing Ji-na really feeling sad because of parting with Seung-min, Hyung-tak doesn't even say that he
can now let her go and tells her to keep her love and regain her happiness with Seung-min.
On the other hand, Seung-min gets advice from his father to fight for his love for Ji-na.
That night, Ji-na meets Han-na and realizes she is not a friend worth fighting for
because Han-na never thought of her as a friend. After severing her friendship with Han-na,
Ji-na told Han-na that she had never snatched anything from her
because Han-na had never had it. Ji-na and Seung-min finally meet again,
decide to re-knit the love relationship, and officially date. A few days later, at school,
Ji-na gets word from her friends that her video on Youtube has become number one trending.
Han-na decides to drop out of school and rework everything from scratch to pursue her dreams.
Ji-na then meets Seung-min on the school roof, where he then proposes a new contract to her,
namely a contract to be in a relationship forever, to which she immediately agrees.
Seung-min is now not shy about kissing Ji-na because they are officially a dating.
The moral that can be learned from this movie is sometimes true love comes from someone unexpectedly in our lives.
Sometimes true love comes from people who look ordinary in our eyes but have extraordinary
hearts and care for us. So, if we have found such a person, never let it go to waste.
