I Confessed and You Rejected Me, Now You’re Crying over a Song?

After being reborn, Chen Mo returns to the class reunion after high school graduation in 2006, to the moment he confesses his feelings to Chu Tongrui.

But this time, facing the girl he had pursued relentlessly in his previous life without ever winning her heart, Chen Mo walks away with a carefree smile. Now that he's been reborn, who's going to be a doormat?

With knowledge of the future and his professional expertise, all Chen Mo wants is to reach the pinnacle of the music industry! But his change in attitude leaves Chu Tongrui completely unsettled.

Chen Mo used to put her at the center of everything. Why has he suddenly stopped paying attention to her? It isn't until she hears the song “Guest” on a talent show that she thinks perhaps she paid too little attention to Chen Mo.

On the day of university registration, she decides to ask him what's going on, only to discover that the campus celebrity and beauty has already walked up to Chen Mo of her own accord. “Chen Mo, thank you for writing this song, ‘Guest,’ for me!”
