Daon might know whom he really likes now but him giving mixed signals is annoying.
Daon says he likes Sunghyeon, thinks about him whenever he's with either Soohyun or Jaemin but Jaemin is always his numoro uno priority.
In chap 99 Daon implied that him having to take care of Jaemin was Soo's fault (Soo hit Jaemin and Jaemin is so mart so he uses it to keep Daon around). Yes, but dude doesn't have to move in with him.
Sunghyeon was right when he said that even Daon was there with Jaemin it wouldn't guarantee either of their safety if Soo decided to make Jaemin a sandsack again.
