In the beginning, the movie shows a scene in San Francisco, USA, in 2008,
when a cruise ship was sailing to Alcatraz Island.
At that time, a beautiful freelance photographer took a short trip to take pictures of tourists.
A pretty woman named Zhao Mo Sheng secretly snuck onto the
ship and offered photo services to the tourists to earn money.
Unfortunately, when a ship's security officer started patrolling,
she had to stop the photo shoot because it was illegal.
A few years later, in Shanghai, China, in 2015, a woman named Hua Xian Zi came to Mo Sheng's apartment to wake her up.
She was Mo Sheng's assistant and had been working with her for the past few years.
Mo Sheng now works as a professional photographer in Shanghai with high pay. After opening every window
curtain, Xian Zi nagged and asked her to wake up immediately as their photo shoot schedule was nearing.
After completing all the preparations, Mo Sheng rushed to the studio to do a photo shoot of some national magazine models.
She was doing her work as diligently as she had been for the past seven years.
After finishing the photo shoot, Mo Sheng went to the supermarket to buy food stockpiles.
But while she was busy buying some drinks, she accidentally saw his ex-boyfriend, He Yi Chen, with a girl in a cafe.
Mo Sheng broke up with him seven years ago after her departure to the USA.
Feeling awkward about the meeting, she intended to hide on the drink shelves,
but she accidentally dropped the pile of drinks next to her.
As a result, Yi Chen and the girl were aware of her presence in the place.
However, Yi Chen was indifferent to her and preferred to leave the area with the girl named He Yi Mei.
The night when Mo Sheng was about to return to her apartment,
the security officer at the supermarket said that she had left her wallet, and he handed it to her.
She initially wanted to refuse the wallet because she didn't feel like she had lost it,
but the security officer said a picture of her was inside it. After checking it out, Mo Sheng saw
her own photo from a few years ago and immediately realized that it belonged to Yi Chen.
She began to think that he still had feelings for her because he kept her picture even after they had broken up for years.
Moreover, she also found the writing 'You are my Sunshine' at the back of the picture,
so she was more and more convinced that he still loved her.
The next day when Mo Sheng was about to take a photo shoot,
Xian Zi said that the model who was going to do a photo shoot that day was a pretty popular one named Xiao Xiao.
Xian Zi mentioned that this model has some particular criteria for every picture she takes and has a lot of rules.
Soon after, she came to the studio, and Mo Sheng started taking pictures under Xian Zi's direction.
In the middle of the photo shoot,
Mo Sheng and Xiao Xiao were suddenly pensive as they realized they were friends from the same university.
In the evening, Xiao Xiao invited Mo Sheng to have a drink at a nightclub to share their stories.
She knew about Mo Sheng and Yi Chen's relationship and thought that Mo Sheng
She denied it and said that Yi Chen was currently in a relationship with another woman named Yi Mei.
Xiao Xiao scolded her for leaving him without any explanation.
She then told Mo Sheng about what he did after she left for the USA.
After that day, he had been waiting all day in the college dorm after hearing that Mo Sheng was going to New York.
Since she left, he became heartbroken and still couldn't turn away from her though he had been viciously deserted.
Before Xiao Xiao left, Mo Sheng handed over Yi Chen's business card.
He has now become one of the most successful elite lawyers in Shanghai.
The next day, Mo Sheng came to the address on the business card to return Yi Chen's wallet.
The night Mo Sheng was still finishing her work at the studio, Xian Zi said a handsome guy wanted to see her. It
turned out that the good-looking man was Yi Chen, who purposely came to ask for the picture she had
taken of his wallet. Mo Sheng refused to give it because it was her picture, and she did not want
him to constantly remember her if it was still in his wallet. Before leaving, he said that he kept
the picture to remember all the sad moments he has chasing her. Hearing that, Mo Sheng could just sit
down and cry while remembering the first time they met. Formerly, Yi Chen was a very cold and
difficult-to-approach law student, but she could make him fall in love with her. The following day,
Mo Sheng sent the picture she had taken from Yi Chen's wallet to his assistant through a
package. She also sent some sweets that she used to enjoy with him while they were dating. Yi Chen
remembered the beautiful times when he dated her and even remembered the moment when he
kissed her for the first time. The next night, Xian Zi realized that Mo Sheng was confused,
so she tried to dress her and take her for a walk to cheer her up. As they were about to leave,
Mo Sheng accidentally met with Yi Chen, who was picking up a girl named Miss Wen. Xian Zi
thought he was in a relationship with Miss Wen and played with Mo Sheng's feelings,
so she scolded him. But Mo Sheng stopped Xian Zi and let Yi Chen go with Miss Wen. After seeing him
leaving with the other girl, Mo Sheng became increasingly moody and decided to return to
her apartment. Shortly after Mo Sheng arrived at the lobby, Yi Chen suddenly appeared behind and
hugged her tightly. He kissed her forcefully as if trying to tell her that he still loved her very
much. He expressed intense pain after she left for the USA seven years ago. The following day,
Yi Chen invited Mo Sheng to go to their university to recall the times when they were still together.
He told her that the law faculty professor who taught them often asked about their relationship.
After spending all day together, he drove Mo Sheng home to her apartment. Before parting,
he apologized to her for what he did last night, and she accepted. Then, their relationship blooms
again because they are still in love. Yi Chen has even ended his relationship with Miss Wen,
the mayor's daughter who's been chasing him. But the next night, Mo Sheng told Yi Chen the shocking
thing that had happened in the USA. She said to him that she had married someone in 2011. It made
him feel broken for the second time because he wanted to reunite with her. The other day, Yi Chen
recalled his childhood memories of when his father died after he ended his life due to the bankruptcy
of his business. Yi Chen's mother once told Yi Chen that the person who caused the date of his
father was Mo Sheng's father, who was at that time a competitor of Yi Chen's business. At that time,
Mo Sheng's father once offered to pay all of Yi Chen's tuition fees abroad, but Yi Chen rejected
the offer because he still remembered the incident that happened to his father. A few days later,
Mo Sheng heard from one of Yi Chen's colleagues that Yi Chen was hospitalized. Mo Sheng went to
the hospital to see him, and that was when she accidentally met Yi Mei. She confessed that she
was the one who sent someone to tell Mo Sheng about Yi Chen's condition. Yi Mei then told Mo
Sheng that he had a pretty acute stomach disease because he always consumed alcohol and became an
alcoholic after Mo Sheng went to the USA. She told Mo Sheng that she was Yi Chen's foster sister and
Yi Mei's parents had adopted Yi Chen since he was very young. Yi Mei once had a crush on him,
but after she realized that the only person who meant anything to him was Mo Sheng,
she decided to let him go. During this time, Yi Mei continued to accompany him, who had suffered
heartbreak for years after Mo Sheng left. After hearing Yi Mei's explanation, Mo Sheng felt very
guilty for what she had done to Yi Chen. A few days after Yi Chen recovered, Mo Sheng went to
see him and told him that she had divorced her husband. Mo Sheng wanted to make up for her fault
and restart their relationship. But Yi Chen said he did not want to accept someone who had belonged
to someone else and then drove her away. In the evening, Yi Chen got advice from his assistant
to lower his ego and compromise to pursue the happiness he had always wanted. The next day,
Yi Chen came to Mo Sheng's apartment, which seemed to need repair, and immediately asked Mo Sheng
to get married at the same time. He asked her to prepare her passport and go to the civil office to
register their marriage. The woman who handled the marriage certificate suggested they postpone their
marriage to another day because it was the unlucky day to get married. But he insisted and processed
all the wedding papers that day. After finishing the registration, he gave Mo Sheng a credit card,
a new car, and a house key. He said his assistant, William, would help her move all
her belongings to their new home. The next day when Miss Wen was about to give Yi Chen a cake,
she discovered that he had married Mo Sheng. Miss Wen said that Yi Chen's relationship with
William was much closer to Yi Chen's relationship with any girl. Mo Sheng also tried to ask William
a few questions to see if Yi Chen was gay. But after Mo Sheng made sure that Yi Chen wasn't gay,
she was relieved. William was an orphan who had been helped by Yi Chen to complete his studies,
so he managed to become a lawyer like Yi Chen. In the evening, Mo Sheng called Yi Chen because he
hasn't come home yet. He said he is currently on a business trip with his client outside the city,
so he could not go home until the next few days. But at midnight, he suddenly appeared in
their apartment and surprised Mau Sheng, who was fast asleep. She asked him to sleep beside her,
but he refused because he still felt awkward about her. The incident made her think that he had no
desire to sleep with her, so Mo Sheng asked her friends the next day about it. Mo Sheng's
friends also suggested that she wear sexy cloth to welcome Yi Chen when he came home. In the evening,
Mo Sheng wore super sexy cloth recommended by her friends and greeted Yi Chen with an erotic dance.
But unexpectedly, he came home with his colleague, and she felt very embarrassed and ran to the room
to hide behind a blanket. The following night, Yi Chen imagined the moment he proposed to Mo Sheng
at a fancy restaurant with a beautiful diamond ring. However, when he is about to propose to her,
they accidentally meet Mo Sheng's stepmother at the store. When he saw her stepmother,
he became uncomfortable and left the store. He recalled his father's death and realized that Mo
Sheng's stepmother was the cause of his father's death. Mo Sheng then came up to him in front of
the restaurant and looked at the surprise Yi Chen would have previously given. She thanked him for
the surprise, but he denied it and said that he was not the one who had prepared the surprise.
Seeing Yi Chen, who seemed upset, she tried to ask what was bothering him at the time, but he chose
not to explain anything. The following night, Yi Chen came to Mo Sheng's apartment because,
on that day, she did not come to his house. Upon his arrival at Mo Sheng's place, he asked why she
did not respond to his call, and she explained that her cell phone had suddenly been off. When
he found her flight ticket to the USA, he scolded her because he thought she would leave him again.
The angry Yi Chen suddenly carried her into the room and intended to force her to sleep together.
But she stopped his action when he discovered she had severe flu. He felt guilty because he
had frightened her, so he decided to leave her apartment. Before he could get into his car,
Mo Sheng ran after and hugged him while saying that she would only be gone for a few days. He
was relieved after knowing that she would not leave him and covered her with his jacket so
that her illness would not worsen. The following day when Mo Sheng woke up in Yi Chen's arms,
she just realized that he had put a diamond ring on her finger. Since then, their relationship has
improved as if the good times they had during dating were repeated. A few days later, when Mo
Sheng was walking around the festival in the city, she was shocked by the showing of her ex-husband.
He was Ying Hui, a successful entrepreneur with many businesses in the USA. Yi Chen has known
about Ying Hui since meeting at an event a few weeks ago. That night, Ying Hui invited Yi Chen
to speak privately about what happened to Mo Sheng in the USA. He told Yi Chen that the
only marriage he ever had with her was a contract marriage. A few years after she moved to the USA,
her family suddenly went bankrupt, so she had to make money to survive by becoming a traveling
photographer around campus. Ying Hui, who felt sorry for her, intended to help. A few months
later, she wanted to adopt an orphan boy named Jack. But to perform the procedure, she had to
handle various administrative letters, so Ying Hui decided to help her by pretending to be her
husband. Over time, he began to have feelings for her, but he realized that she still loved Yi Chen
very much. He found out about Yi Chen when he was hospitalized for a gunshot wound caused by
Jack's biological father. At that time, Mo Sheng was waiting for him all day in the hospital,
and at that time, he saw Yi Chen's name on her laptop. Then when Ying Hui learned that
the relationship between Yi Chen's and Mo Sheng's families had a bad history, he intended to take
her back because he was afraid that Yi Chen would hurt her. However, Yi Chen convinced him that he
loved Mo Sheng very much and would never hurt her. The next day, Mo Sheng's stepmother, Aunt Pei,
came to Yi Chen's office after she found out that he had married Mo Sheng. Aunt Pei wanted to ensure
that he didn't marry her just to take revenge for what her father had done because she was innocent
of his father's death. Yi Chen also said he had no intention of revenge on Mo Sheng's family,
and even he asked Aunt Pei to hide the secret about his father's death from Mo Sheng. Sometime
later, Mo Sheng and Yi Chen went on vacation to San Francisco and sailed on the boat
she used to ride. She accidentally met her fellow photographer, who used to take a picture of her
while she was in the USA. When she saw the photos from the old album belonging to her colleague,
she found Yi Chen's picture on the back. She finally realized that Yi Chen had once followed
to look for her for the first two years after moving to the USA. The film ends with the scene
where Mo Sheng hugs Yi Chen with guilt for all the struggles he has ever done for her. The moral that
can be learned from this movie is never to disappear without explanation, leave without
giving a reason, and never waste the sincerity of those who love us wholeheartedly.
