guys, i also don't like the fact that Han Gyuol forgave him so fast and easily, but you seem not to understand the fact that it was literally an intention of the author to show the abnormality of Han Gyuol's attitude here... You seem to forget that Han Gyuol is traumatized as he** and he finds comfort in attachments to somebody. Both Han Gyoul himself and other people around him, for example purple haired guy, said that when mc loves somebody he loves them to the fullest. To the bottom of his heart. It wasn't specifically mentioned, but most likely Han Gyoul gives all of himself to the person he fancies and therefore is unable to keep his own boundaries and build the healthy relationships, because he unconsciously tries to merge with his partner... That's exactly what we see here and earlier. It's just trauma response, not that he's an idiot or smth.
