L-DK begins by introducing us to Kageyama Shuusei, a teenage boy who is very popular at his school.
But even though many girls admire him and wish to be his girlfriend, Shuusei doesn't really care about them.
One of the girls who have a crush on Shuusei is Moe.
But unlike the other girls who could only scream hysterically when he showed up,
Moe intended to express her feelings to him.
She had even told her plan to her best friend, Aoi, who supported her wholeheartedly.
But unfortunately, when Moe confesses her feelings to Shuusei in front of the students, he coldly rejects her.
She was undoubtedly very embarrassed by the rejection.
And the students laughed at her instead of comforting her.
Angered to see her friend humiliated, Aoi went to Shuusei and scolded him.
But instead of apologizing, he teases her because he thinks she also wants to confess her feelings to him.
She was even more furious at the baseless accusations.
She reflexively kicked him, causing him to fall down the stairs and sprain his leg.
As a result, she had to carry him home.
She felt guilty for hurting him, after all.
But to her surprise, it turns out that Shuusei lives in the same apartment building as Aoi.
Not only that, their rooms are even opposite each other.
She only found out about this fact because he had just moved there not too long ago.
Anyways, after she escorted him to his room, Shuusei asked Aoi to make some food for him,
telling her that his legs still hurt from walking.
So, having no other choice, she reluctantly complied.
When Aoi was just starting to cook, Shuusei approached her from behind, startling her.
His behavior caused her to lose focus, so she poured too much sake oil into the food she was cooking.
Needless to say, it ignited a fire that soared from the pan, activating the fire detector.
And it didn't take long before the water started pouring down profusely, making Shuusei's room completely wet.
As a result, Shuusei had to change rooms while his room was repaired.
But since there are currently no vacant rooms, Aoi is forced to let him stay in her room for a while.
However, she felt a little responsible for the incident. Despite this, she was actually
very annoyed with him, especially since he behaved so casually when he was in her room.
He even only wore underwear when he finished taking a shower.
The next day at school, Aoi hears about a pair of students who secretly live under
the same roof has been expelled from school.
The news scares her, so she tries to avoid Shuusei at school. She didn't want others to know that
they were living together, and minimizing contact with each other would minimize the risk of people
finding out about their situation. But that plan was ruined instantly after Aoi bumped into Shuusei
in the school hallway. He even gave her the key to the room she had left behind right in
front of her friends, including Moe. Panicked, Aoi immediately drags him out of the way of her
friends before telling him that she doesn't want others to know that they live together.
Let it remain their secret. Moe was a little jealous when she saw Aoi and Shuusei acting close.
And moreover, why did Shuusei bring Aoi's room key? After telling Shuusei, Aoi returns to Moe and
the others, informing them that she accidentally dropped her room key, and then he finds it to
return the key to her, that's all. But of course, Moe did not necessarily believe that explanation.
After school, Aoi posted the rules regarding what Shuusei could and couldn't do on the room's wall.
But just as she finished working on it, he came home with a friend, Sato, forcing her to hide.
He noticed that she was hiding under the blanket, but he purposely sat on her and tickled her feet.
Obviously, that pissed her off, so she got up from under the covers when she got the chance,
intending to leave the room while Sato was on the balcony. Sato notices her presence,
but luckily, he believes when she claims she is Shuusei's neighbor. The next day,
the landlady invites Aoi and Shuusei to attend a barbecue party that will be held next week.
She allowed them to invite their friends if they wanted. Hearing that, Aoi planned to take Moe
along. Incidentally, a few moments later, Moe came to the apartment. Although, she came at the wrong
time because Aoi was standing beside Shuusei. Moe is dumbfounded to see the two of them together,
and Aoi frantically tries to explain what really happened between them. Ultimately,
she convinced Moe that Shuusei had just moved into the apartment building. But she didn't tell Moe
that they lived together. A week had passed since then, and they were now attending a barbecue.
Shuusei brought his brother, Soju, and Sato, while Aoi brought Moe with her. Here, Aoi plans to tell
Moe the truth about Shuusei. But before she could say it, their attention was drawn to a woman who
suddenly came up to them all. It turns out that she is Satsuki, Shuusei's childhood friend and
ex-girlfriend. The atmosphere inevitably became awkward, especially since she was cold to Aoi.
Regardless, Aoi and Moe got to know Sato better at the party and even acted like close friends when
the party ended in the afternoon. But then, Satsuki approached Aoi while she was alone
packing things into the car. She notices that Aoi is close to Shuusei and doesn't like that.
So, she warns Aoi not to fall in love with him because it will only waste her time.
No matter how she tries, Shuusei will only love Satsuki. In response, Aoi tells Satsuki that she
has no feelings for Shuusei. Therefore, Satsuki needn't worry. But, as if not believing her words,
Satsuki just looked at her with scornful eyes before walking away. A few days later, the kind
landlady gave Aoi two amusement park tickets, who immediately planned to take Moe with her.
But suddenly, Shuusei snatched a ticket from her hands, saying that he would accompany her to the
amusement park. After school, Aoi is seen waiting for Shuusei at the amusement park,
wondering why she can't refuse him even though she hates him. And speaking of the devil, he came
a few moments later and dragged her to try some rides at the amusement park. But unexpectedly,
she really enjoyed the time she spent with him. After playing, they choose to relax at the cafe,
where Aoi sees a poster for the fireworks festival that will be held next week. She wanted to go to
the event. Moreover, it was said that the couple who kissed when the seven fireworks were lit would
be blessed. Unfortunately, she still doesn't have a man she can take there with, let alone
a boyfriend. Hearing that, Shuusei offered to go with her to the festival, as he thought it would
be interesting. The next day, Aoi finally decides to tell Moe about her feelings for Shuusei.
She apologizes to Moe because, although she hated him at first, she has fallen in love with him
now. She knew Moe liked him first, and she knew that her confession would hurt her. But still,
she prefers to be honest with Moe rather than hide her feelings. Hearing the shocking confession, Moe
couldn't hide her disappointment. But in the end, she admits she has no chance with Shuusei. He had
rejected her, after all. And more importantly, she still wants to be friends with Aoi. So, she gave
her blessing to her while promising that she would support Aoi so that she could be with him. On the
way home after school, Aoi and Shuusei passed in front of a jewelry store that displayed necklaces
in the front window. She wanted the necklace but didn't have the money to buy it. Maybe right now,
she was hoping Shuusei would buy it for her. Unfortunately, he just stood there quietly before
leaving. When they arrived at the apartment, they found Satsuki already standing waiting in front of
their room. But Shuusei didn't care about her at all. He walked past her and then entered the room.
Satsuki is clearly unhappy that Shuusei lives in the same room as Aoi. She again warns Aoi, saying
it would be a waste if she loved him because he has a secret that only Satsuki knows, and
that's why they can't be separated. Aoi is clearly annoyed at Satsuki, who still dares to threaten
her despite her long breakup with Shuusei. But Aoi just kept quiet in front of her. The
next day after school, Aoi meets Shuusei's older brother, Soju, who tells her about their family's
dismal condition. It turns out that Shuusei has always lacked affection from his family,
and that's why he always acts cold towards people. Only Satsuki, his childhood friend,
always gives him attention even after he grows up. But then, Soju stopped his story and kissed Aoi.
Needless to say, she was shocked and angered by his action because it was her first kiss.
Soju's lecherous behavior finally reached Shuusei's ears. He immediately went to his
brother at work to beat him. After that, Shuusei met Aoi, who was crying alone in a park. He asks
her to stop being naive because it makes people easy to fool her. Eventually, he managed to
calm her down. They even had fun and laughed together there. As the days go by, Aoi's love
for Shuusei grows, to the point that she changes her appearance and cuts her hair to impress him.
Not only that, but she prepared lunch for him when he started working part-time at a restaurant.
Even so, they still keep their distance from each other at school. But one day, Satsuki suddenly
called Shuusei, and whatever she said made him uneasy. Then, without explaining anything to Aoi,
he went to meet Satsuki. But despite his attitude, Aoi kept waiting for him until her phone finally
rang. Thinking it was a call from Shuusei, she immediately picked it up without checking the
number. But she was wrong. It was a call from Satsuki, telling her she would have fun with
Shuusei tonight. Of course, her words made Aoi both sad and angry. A fight was inevitable when
Shuusei came home. Because of that, he decided to leave the apartment. But still, Aoi wants to know
what really happened between Shuusei and Satsuki. So, she chased after him in the pouring rain,
demanding an explanation. But he remained silent. He left her feeling confused. The next day at
school, Aoi is surprised to see that Moe is dating Sato. But during their excitement, they realized
that Aoi was not as usual. She looked gloomy, and Sato thought it had something to do with Shuusei.
Feeling sorry for her, Sato then tells her about the problems that happened to Shuusei and Satsuki
two years ago. At that time, Shuusei and Satsuki often quarreled, and they even bickered in front
of Sato. Even so, they still try to maintain their relationship. But on Christmas Eve,
he suddenly becomes uninterested in her. He didn't even want to see her anymore. Of course, that
pissed Satsuki off. She kept calling Shuusei, and when he finally picked up his phone, she told him
she was tired of everything. She intends to end it all. Feeling guilty, Shuusei looked for Satsuki,
who he later found was already unconscious. Her life was finally saved after being rushed to the
hospital, but he couldn't shake off the guilt he felt for her. He even still feels guilty
towards her to this day. After listening to Sato's story, Aoi decided to go home, and it was when she
arrived at her apartment door, she found a small pouch on the doorknob. To her surprise, it turned
out it was the necklace she wanted. She knew no one else could give her that other than Shuusei,
and knowing that fact brought her to tears. Days passed, and Shuusei kept himself busy with his
part-time job. Until one day, Soju meets him to give him a piece of his mind. In Soju's eyes,
Satsuki had been fooling him all along. She just made him a doll she could play with as she
pleased. Soju wants him to no longer feel guilty about what happened to Satsuki in the past. Soju
will take care of his problems with Satsuki as long as Shuusei keeps fighting for his true love.
At the same time, Aoi is seen packing Shuusei's belongings before she looks at the necklace he
gave her. A few days later, Aoi plans to go to the fireworks festival with Moe and Sato.
But when the bus came, they told Aoi to go first while they would catch up with her on a motorbike.
But they actually lied about it. In fact, they went to Shuusei to inform him that Aoi was
currently at the fireworks festival and that he needed to get there soon. They told him that the
necklace he gave her hurt Aoi's feelings because, after all, she still didn't know how he felt about
her. And so, Shuusei went to the festival location on Sato's motorbike. He realizes his feelings for
Aoi are true along the way there. He just couldn't let go of the past. At the end of the film,
Shuusei finally meets Aoi, and the first thing he does is apologize to her. It just so happened that
fireworks had lit up in the sky, and he naturally didn't want to waste this moment. He kissed her
and then confessed his feelings to her. And the film ends with Shuusei putting the necklace on
Aoi. So, is your high school romance as dramatic as the story of Aoi and Shuusei? Or maybe you
can't forget your sweetheart during high school even though they are married to someone else?
Hey, if there's one message we can take from this film, it's that we must let go of the past.
