Heesoo is the only character here with some goddamn rationality! seriously

nah there was no rationality in his actions. Hyesung was seriously traumatized and he tells him to "shake it off"? and bringing in Byul when Hyesung is suffering himself? yeah it’s just insensitive

Completely agreed. You can't just tell someone who's very clearly mentally exhausted to "shake it off" wtf.
