I understand his feelings. - He may be afraid to change their actual relationship, changing things can be frigthening. You can lose all you have built until now. Friends that become lovers, know that if their relationship doesn't work, they'll not only lose their lover but break the friendship they hold dear.... - And if he's inexperenced in love, it's even harder. So him being hesitant, confused & frightened by the situation is quite normal (like I was xD).
It's a little bit coward & egoist but that's how human are lol.
I just don’t get why seungtaek won’t be straight forward and reject kyunbin but he does like him he even admitted it to the perv guy. If seungtaek doesn’t want to let him go and he doesn’t want to admit his feelings just what is he gonna do. (╯°Д °)╯╧╧
