The talented pianist Shen Xinglan temporarily left the stage due to a mental disorder and entered an ordinary university anonymously, where he met Lu Chenyu, a seemingly unruly top student in the mathematics department. An unexpected "share house" binds people from two worlds together. Under Lu Chenyu's invisible protection and guidance, Shen Xinglan stepped out of the shadows step by step and regained her dreams.

They are each other's stars, redeem each other, and on the stage of youth, they jointly compose a gorgeous movement about love and dreams.
