WAIT WAIT WAIT... BACK UP A SECOND... I thought he liked him WTF!!! Is it because he does ...

my theory is that xuan run (i think that’s the chinese guy’s name) is in denial about his feelings for siwon (the uke). when siwon was being so kind to him, a switch flipped in him and he got pissed off — most probably because he’s starting to feel things but he doesn’t want to admit it, so the best way he deals with it is by being a jerk and wanting siwon to hate him. he maybe thinks that by hurting siwon and causing him to suffer, siwon would see that his words to him in the dream (worrying about him — even though he actually saw jinha, asking about what hurt him, etc.) was all a lie and that siwon is actually a jerk himself.
