I don't get why the professor's "interested" in wooju, like Wooju doesn't even seem like his type at all,, I reckon Professor Cha and Jiheon might've had some beef in the past? maybe something happend between them and that's why prof Cha has the scar on his forehead,, idk it just doesn't add up how professor Cha's meddling with Wooju and Jiheons relationship,, Ohhh I wanna know more about their past now!
