Yeah, so Guwon is basically a grown-up who acts like a child.
He doesn't really understand the implications of everything that has happened, or even the things he himself has done so far. It seems like he does things just for the fun of it, because they make him feel a certain way. He seems to get a lot of satisfaction from being liked or needed by the people around him.
The fact that he can only really get along with the kids in the group says a lot about him and his personality.
Guwon obviously doesn't like the teacher romantically, but he definitely enjoys all the time, care, and attention he gives him + he's the only adult in the group/community who isn't really afraid of him. So he's been humoring the teach just to stay on his good side and get his approval (spoiler: he finally did it!!!!)
All of this makes a lot of fucking sense once you look up a little into the myth that the story is based on. Sisyphus is egoistic and narcissistic by nature, he often manipulates people in order to get what he wants without thinking too much about the consequences of this. Thus, this way of living earned him a big punishment from Zeus that got his bitchass humbled lol and well... you know the rest.
Bet that the author is going to redeem this ugly duckling for all of the sins he has committed and I'm totally up for it
No matter how many times I read this story it will always be my favorite TT
