Well the professor was probably naked because he just came out of the shower and/or could’ve been in the middle of sex because he seems to be having his rut since the other guy was overcome by pheromones.
The only friends he has were with him camping and they already gave him the 3rd degree about his behavior changing so he probably doesn’t want to talk to them. For the parents part, how often do you go to your parents? Just because he seems close to them doesn’t mean he tells them everything or wants to make them worry especially since they have trauma too from when he got kidnapped.
The professor is his mentor and Wooju talked about the professor‘s father helping him before plus it seems like he’s talked about Jiheon to him before.
I don't understand why he's naked? I don't understand why the MC would go to him when he has his friend and parents. Mr. Cha was just some guy he works for??? I'd never go to my boss with my personal.issues??
