TBH I don't think he doesn't know or is doubting himself because of what happened back in High School when he said that he didn't like him but I get where you're coming from it is kind of annoying
Simple hes embarrassed wouldn't you be if a man or woman was taking your clothes off at a motel
He was blushing and getting nervous even before that scene(taking off cloth) happened
I mean the other guy is smexy but he walked in half naked
Why the fuck is woojin blushing with other guy I just cant understand I hate it. Why agree to go motel with black haired guy even when he knows that guy likes him. Getting nervous my foot woojin I dislike you.I started to feel that he doesn't like my Sangyoon. He doesn't deserve Sangyoon.
