: Due to the death of Bai Yueguang (Chen Yu), the female protagonist uses the male protagonist (Li Yuan) who is 70% similar to Bai Yueguang as an emotional substitute. She approaches with a clear "purpose" in the early stage. However, the male protagonist has been secretly in love with the female protagonist since college and is willing to sink despite knowing that he is a substitute. This is an unequal relationship in which "one party uses it and the other tolerates it".
