i thought that maaaaybe the doc knows the mc for a long ass time,, and since he is a plastic surgeon, he could have got a plastic surgery (?), so the mc cant recognise him nowadays...
i dont think he's a bad guy, but something is up for him to "like" the mc easily like that. maybe the guy who's friends with mc is part of some kind of plan;;
since the mc "fell in love" for the affection he never got until now, i understand the anxiety he's feeling towards the doc. i've been in love for four years now with the same guy and everytime someone else is kind in a romantic way to me, its like i'm falling in love with this other person, but it always feels like something's missing... and the fear of never being reciprocated causes you to rely on them even more than before.
coming back to my theory... like i said before i dont think the doc is a bad guy, but i think he'll hurt the mc feelings, and then he'll know he truly loves him...or he already does love him or whatever,,,
so um... he doesn't even have a pigeon chest- it was weird
