Yi Nan never cares about Jiang Yan's attitude towards him. He is still a love letter and an early bird. He follows her home after school every day. He talks a lot and often tries to find topics. Although he can't get Jiang Yan's response, he is always happy.

Jiang Yan always thought that she hated this boy very much. She wanted him to disappear from her side. Only one day, Yi Nan didn't come to class, there was no breakfast and love letter on the table, and she came home from school alone. There was no noise in her ear, so she felt empty in her heart.

Because she was absent-minded, she didn't realize the potential danger around her. When she passed a dark alley, she was pulled in with both hands. The man covered her mouth and dragged her to the end of the dark alley. At the end of the alley was a wall. She was thrown up. Then the man moved to her. She trembled and struggled with fear.

"Hiss" a, the white shirt was torn, her hands protect, can only sob in a low voice, just when she thought she was finished, a flashlight light shot in, and then she saw a young man ran against the light, grabbed the boy who wanted to insult him, mercilessly beat.

It was Yi Nan, who appeared when she needed help most, and let her know that he had already lived in her heart unconsciously.

Yi Nan takes off her clothes to wrap her and send her home. When Yi Nan turns to leave downstairs, Jiang Yan suddenly stops him and agrees to his pursuit.

Since being with Yi Nan, Jiang Yan has been learning to smoke, swearing and playing truant in order to integrate into his circle. She thinks she will feel guilty when she does these things, but what she really does is feel more relaxed than ever before.

Before those aura pressure her breathless, now she can really fly self, she can wantonly yell in the back seat of the motorcycle, regardless of other people's eyes, make-up, puff.

Her grades began to plummet. The teacher talked to her and asked her to invite her parents. She didn't care. As long as she could be with Yi Nan, she was not afraid. But one day Yi Nan broke up with her and said that she had never liked her. She pursued her just because she had gambled with her brother. By the way, she also wanted to see what a good student's degeneration looked like.

Every word is like a sharp awl, hard chiseling Jiang Yan's heart, she went home, shut herself in the room for three days and three nights, the fourth morning put on the long lost school uniform, comb the ponytail, return to her kaolin, be a good student, a good child, a good example.

And she will never know, Yi Nan is because after the last lesson intended to belittle her person, and the man to find Yi Nan alone, Yi Nan ignored, he said a lot of insulting Jiang Yan words, Yi Nan angry, but fight with him, but mistakenly killed him.

Because minors, although not sentenced to death, but the best years of the rest of their lives are spent in prison.

After he killed the man by mistake, he ran to Jiang Yan for the first time and turned himself in after saying that. He didn't want Jiang Yan to wait for him. He didn't want Jiang Yan to feel guilty and sad.

The ending of the story is that Yi Nan is released ahead of time because of his good performance. He lives a hard life at the bottom of the society and depends on selling coolies to support himself. One day, he meets Jiang Yan by chance. At this time, Jiang Yan is married and has a son. The three members of the family are very happy. They meet, smile, say hello, and then walk away.
