Mo Youzhi and Gu Ye are two people who grew up in the same ruins. She was trapped in the shell of "someone else's child", trying her best to break herself to take a breath; he lived alone in silence, full of loneliness that no one knew about. He handed over the cigarette and she took it without saying thank you to anyone. He watched when she was broken, and when he didn't move she squatted next to him and smoked. No one pulled the other to the shore, but just let each other know that brokenness was never alone. Later, when she was homeless, he stretched out his hand and she put it in. The two of them walked forward together and never looked back.
Purpose: The original family brings spiritual shackles, allowing two scarred teenagers to empathize with each other and accompany each other, and never look back.
