Have you ever thought about finding someone exactly like you to live in your place? After discovering that he was infected with AIDS, Yin Chang cloned a healthy self at the cost of his life. But this clone possesses all of Yin's knowledge and abilities, but lacks all of Yin's memories. Yin Chang needs to teach him all the memories that can ensure that the clone can seamlessly take over his life six months before the payment deadline. These six months have been a time to re-examine my past and see through some of the things I once resented. The misunderstandings of youth, the loss of life, and the messy worries of youth, Yin Chang is teaching others, and he is also teaching himself that what is not worth mentioning before leaving, and what he has never cherished. The six-month deadline has expired, how should Yin Chang choose? And what was the reason for his illness? Who is going to leave all this to explore? The sunshine in Qingcheng is the eternal secret in the hearts of these people in the story. This is a plain in the north, where blazing winds often pass by on summer nights.
Concept: Youth seems calm, but secretly it is turbulent. We have no right to decide anyone's life, we must believe in love.
