Twenty-two-year-old Yun Yichen thought that Cang Ye was a sudden fire in his frozen world. He devoted himself to this love like a sacrifice, but he didn't know that he was just the shadow of another person - Gu Xuecheng, the Bai Yueguang whom Cang Ye fell in love with, and the heir of the Gu family whose features were similar to his.
This is a misplaced love that begins with a substitute. Cang Ye used tenderness to weave a cage, and actually did harm in the name of possession. Yun Yichen jumped from the second floor in despair, breaking his painting hand and all his delusions. After waking up, he chose the most complete escape - oblivion.
Five years later, filming of the movie of the same name began. Yun Yichen plays the "stand-in", and Cang Ye is the special consultant. In and out of the play, the snow remains heavy, and old friends reunite. Only this time, everyone is trapped in their own endings: Cang Ye will miss him for the rest of his life, Gu Xuecheng will wake up in loneliness, and Lin Chen will stop in front of the unfinished painting.
Love is both a prison and a salvation. But some snow will never melt again after it falls; for some people, missing it will last a lifetime. When the final applause rang out, no one knew that this grand and painful youth had already collapsed silently between reality and fiction.
