Obviously the mc is a hyper independent person since he had to take care of everything by himself . Thats why he's acting like this
Uhhh just cause someone gives you money doesn't mean they have control over your life, tf? He thinks he has control over Yeomin. That is what hurt Yeomin's feelings. If Taesoo had said he did it out of affection, maybe that would have softened the blow. But no, instead he refuses to say anything reassuring and confirms Yeomin's fear of only being seen as some kind of prostitute and someone he feels ashamed of. Taesoo constantly tells him how pathetic he thinks he is. And like sure Taesoo gives him all this money now. But how does Yeomin know he wont get bored and toss him out whenever he feels like it? Yeomin can't read that mfers mind.
Obviously his methods sucked but he got rid of ur debt and don’t act like u could ever pay off ur tuition and run away from loan sharks forever likeee i feel bad cuz the top is an asshole but bb he takes care of u
