I think what heejae told tampon was necessary for him, for some sort of closure, that no matter what he does, it won't matter to the prof, I'm not saying what prof did in the past is okay, and I'm thankful that heejae is more self conscious, I hope he suffers a lot, with regarding to facing what wrongdoings he has done, bcs what is the point of many people here wishing him to suffer without wishing he would change for the better too? I think that's kinda immature and childish
