Music composer Yao is at the peak of his career when a brain tumour surgery leaves him with anterograde amnesia. As such, his memory `resets` everyday, that he can only recall past information but not new events. Unable to perform the simplest day-to-day tasks on his own, Yao hits rock bottom until meeting his psychotherapist, Xingyue.

Two "best friends" and rivals reignite a years-long rivalry that only grows more intense when a beautiful young woman enters the mix.
