Yeah, if that were the only circumstances, it is dumb to be mad at someone for not remembering what you did or told them when they were drunk.
He should have told him when he was sober, if he didn't have the courage to do so, it's his problem not Siwon's.
And also, he said: "you were the one who came on to me". But I only saw him clinging to him while DRUNK... Maybe he becomes gayier when he drinks...
I think I understand why siwon doesnt remember jinha, maybe because when siwon meet jinha in their childhood, jinha wear a mask (see the flashback and the picture siwon draw, jinha wear a mask)
and jinha name change too, no wonder siwon dont recognize jinha
and maybe at retreat, jinha already confess everything to siwon (about him being siwon childhood friend and the picture drawn by siwon) but unfortunately siwon drunk and of course he cant remember after he sober
after the retreat, siwon who doesnt remember anything from retreat back to himself and of course forgot about jinha and it lead to siwon ignoring jinha
