When a character is so idiotic, dumb and pathetic that his only defense is bringing down other character .... okay.
Jinha is a boring, pathetic guy too for chasing this dumb guy who can hardly give him a kiss and it's now having BDSM sex massage with somebody else. Okay, and like the Siwon's apologists do ... blame Jinha or at least lets drag him to the mud too so Siwon doesn't look the massive failure of a character that he is. Okay.
"Obviously Siwon is not anyone's favorite character right now " ... Well, that is an understatement. Siwon has been awarded the dumbest uke in Yaoi/Shounen ai and he has earned it with flying colors. I mean, going for drinks with the guy you know already drugged you once is not an easy thing to achieve in terms of stupidity in fiction. At least he seems to be enjoying the BDSM feather massage.
Obviously Siwon is not anyone's favorite character right now, but let's also not forget that for like half the story Jinha was a gigantic asshole. I don't think anyone needs an explanation for Mr. Love Triangle.
If anyone, Siwon's friend (the one who got punched by Jinha) is the only one who deserves to be happy. ┗( T﹏T )┛
