I recently finish My military valentine and it reminded me a lot of king2hearts. As I was about to rewatch it, I remembered the emotional drama it had. I don't have the time or the energy to go through a very emotional drama so I'm looking of a light and quick drama.
lovestruck in the city (its fresh and doesnt have much unecessary plots focuses on the characters and their love stories) soundtrack #1 (my personal favourite) put your head on my shoulder (cdrama but very comdorting and soothing)
