For him, putting on a cute act to hide his cruel, lying nature is the easy way out. If he had said no, Woojon would've left and Siwon would've been left alone again—and I can practically feel his loneliness in those panels. So, why did he go for the kiss? Because, as we well know, he's only after sex and superficial company. Lying comes naturally to this jerk... because he has never been in love!

I had to stare at my wall for straight 10 minutes after completing the recent update., what- what is even happening.. what goes on in siwon’s head– what!—??-???? I’m so fucking confused rn, so does he like like woojoon or not? And like honest to god I cannot bring myself to blame siwon too because wtf are you supposed to do to the guy who suddenly shows up at your house drunk??? BUT ACTING ALL CHUMMY N KISSING THE GUY YOU CALLED BORING AND LEFT HANGING AFTER HE CONFESSED IS ACTUALLY FUCKING CRUEL I AGREE W WOOJOON!!! Im just— he scares me man, what goes on in that fucking hollow shi he be calling his head I fucking wonder
