Probably bcuz he loves Doyoon more. I mean, no way Seunghoo gonna choose that guy just after a few weeks(?) and that's how every plot about 2nd male character since they will end up alone no matter how kind they are
because in the span of those few weeks he showed him more love, care and attention than Doyoon did for YEARSSSS, ugh but ye you're right abt the plot thing ┗( T﹏T )┛what can we do...
Joonyoung deserve someone better than seunghoo, seunghoo isn't worth it.
dammit i almost loved everything but then it all went wrong when seungho chose doyoon over joonyoung lmfaooo nO bruh it doesn't sit right w me i mean that guy literally left seungho and it was joonyoung who took care of him until he was okay again and at the first chance he gets he immediately goes running back to that psycho??? who was the reason everything went wrong btw like wtf jOONYOUNG DESERVES BETTER everything was going gREAT WHY DID HE HAVE TO GO RUNNING BACK TO THAT DOYOON NO WHAT NO AAAAARRRRRRGGGGGHHHHHHHH
