The thing that made this story interesting was the soul switching but now that he knows everything it has become a the regular mundane cliche love story.
They could've kept it interesting if Gyeol had a hard time accepting Doyoon in his new body or Doyoon not accepting himself. Or maybe past Doyoon's family had secrets that the now Doyoon would uncover.
Anything would do.
I am over this nothing happens love Stories
