I mean I get he has trust issues but he really expects a lot out of people without offering anything back. He doesn't say anything about his feelings, or insecurities, or wishes but still acts like he expects everything to work out easily. He's also really quick to judge and is immature.
Like I get that's the entire point of his character and someone loves him BECAUSE of all of that and you know what bro you do you but as a reader, I just get annoyed after a while.
While I feel bad for Hyeseung and understand he's had a difficult life and there are reasons for his behavior and he deserves better, I actually don't like him much.
