Zhu Yu has lived in the neglect of her native family since she was a child. She is scarred and guarded.
An encounter on the rooftop allows Xu Yuezhao, a top student in No. 1 Middle School, to break into his gloomy vocational high school life, melting his loneliness a little bit.
When the training camp expires, Xu Yuezhao returns to school, his friend Jian Du graduates and leaves, the excitement fades away, and Zhu Yu later realizes his fate.
Facing the other party's sudden Christmas confession, his strong inferiority complex caused him to keep escaping and arguing. The night before New Year's Eve, he tacitly allowed the other party to enter his private space, and the two revealed their feelings.
Family conflicts overwhelmed him again, and he returned to the rooftop. When he was on the verge of despair, a soft corner in his heart made him give up his fall.
The Xu family extended a helping hand and adopted Zhu Yu. He took a year off from school and was tutored by Xu Yuezhao, slowly getting out of the haze of the past.
Intention: Long-term loneliness and the redemption of the ever-worn heart
