So far I’m loving this series, I like both of the characters. Also I see both sides POV, so I can get why they're acting like this. The only problem I have is with people judging it before we get to see anything. As we can see on chapter 15, jaeyoung is actually trying to get sangwoo to notice him more than what sangwoo already thinks of him which is a scumbag.
I get why people are mad with the path jaeyoung choose. But the other methods he has been trying to use didn't work as well. Which is leading him to think he needs to harass him which is not good at all and you shouldn't do that to people no matter what happens.
As of rn, we don't know what's going to happen. But what I think it's going to be is a love-hate relationship. I respect other people's opinions on this manga. But honestly, some of y'all are reaching way too much then y'all should be.
