This film tells the story of the protagonist Shen Ping, who works as a tutor at the home of Xiao Wei, who is preparing for the college entrance examination, in order to reduce the financial burden of his girlfriend Junzi. As they get along with him, the relationship between the two undergoes subtle changes.

When Shen Ping faces Juanzi and Xiaowei, what choice will he make... Shen Ping met Juanzi in high school and fell in love with her.

After Shen Ping was admitted to a university in Beijing, Juanzi gave up the opportunity to go to university for him and came to Beijing with him.

Juanzi works as a greeter at a KTV to earn money to support their lives.

In the summer of his junior year, in order to reduce Juanzi's burden, Shen Ping found a part-time job as a tutor for Xiaowei, a girl preparing to take the college entrance examination.

Xiaowei's parents work in Wuhan, and she has been living with her grandmother.

The loneliness of growing up and the college entrance examination brought a lot of pressure to Xiaowei. Shen Ping's appearance and help made Xiaowei feel warm and rekindled her confidence.

Spending time together day and night made the two gradually become familiar with each other, and Xiaowei began to have a crush on Shen Ping.

Just when Xiaowei mustered up the courage to confess her love to Shen Ping, Shen Ping suddenly received a call from her mother, saying that her grandma was seriously ill and asked him to come back quickly.

At the farewell station, Xiaowei gave her amulet to Shen Ping.

On the first day of the college entrance examination, Shen Ping rushed back from his hometown, sent blessings and encouragement to Xiaowei, and hung the amulet back around Xiaowei's neck.

After Xiaowei finished the exam, she finally confessed her love to Shen Ping.

Shen Ping's emotional balance favored Xiaowei.

He went out to meet Xiaowei on the pretext of looking for a job interview.

The considerate Xiaowei never mentioned Juanzi and didn't care about Shen Ping's forced break of the appointment. Therefore, Shen Ping cherished Xiaowei very much.

Shen Ping couldn't live without Xiaowei, and he felt he owed a lot to Juanzi. His conflicting feelings caused Shen Ping to fall into an abyss of pain and be unable to extricate himself.

One day, Xiao Wei and Shen Ping met Juanzi in a bookstore. The three of them were a little embarrassed. The kind-hearted Xiao Wei wittily resolved Shen Ping's embarrassment.

Juanzi recalled what happened during this period and saw Xiaowei's unsuccessful cover-up, which made her suspicious of Shen Ping.

Chen Yu, who had been classmate with Xiaowei for six years, couldn't bear to see the lovely Xiaowei sink deeper and deeper into this fruitless love, so he took the initiative to find Shen Ping and persuade him to choose between Xiaowei and Juanzi.

Shen Ping felt that he could not bring Xiaowei happiness and was determined to end the relationship.

While talking to Xiaowei, he received a notice from the hospital.

It turned out that Juanzi had a dispute with Liu Changfu, the boss of a certain company who had been pursuing her after get off work. Liu Changfu accidentally pushed Juanzi to the ground, and Juanzi fell into a coma due to a head injury.

Shen Ping and Xiaowei rushed to the hospital.

Seeing Shen Ping's nervous look and distressed expression for Juanzi, Xiaowei walked out of the hospital sadly, but met Chen Yu who came after hearing the news.

Chen Yu didn't know how to comfort the injured Xiaowei, so he expressed his feelings to Xiaowei in desperation, and the two broke up unhappy.

Shen Ping looked at Juanzi in a coma, recalled the happy time the two had spent, and decided to give up Xiaowei, whom he loved deeply.

Xiaowei didn't want to put Shen Ping in a dilemma and decided to withdraw from their lives.

Shen Ping went to the hospital to visit Juanzi, but learned that Juanzi had been transferred to another hospital.

The doctor handed the letter written by Juanzi to Shen Ping.

Xiaowei left Beijing to go to school in Wuhan, and Chen Yu came to the train station to see her off.

The two agreed to be lifelong friends.

The train started to move, but Shen Ping could only hide in the corner of the platform and watch Xiao Wei leave.
