Comparing to the other no-heart bich guy in other bl story, he is still far better, I mean at least he has reason why he's messing with sangwoo. Just remember he did try to resolve the graduate matter with sangwoo in peaceful way, but sangwoo just run away. In this case, for me, both are in the wrong.
But yeaah, i guess make him couldn't take the class is a little bit to far... And following him everywhere like that, indeed it's creep.. But I still ship both of them, I wonder how the author will change their relationship, I hope something good will happen next
BTW, THANKS FOR TRANSLATING 💞💞💞💞
