Obviously it was one of his jealous friend that did that hex to him it would be nice to atleast confront that friend so we can know the reason why he did it
I felt like it was the put together friend, but the scene cut off so early and I couldn’t figure it out. Another theory was the friend who started complaining when the put together friend got there giving the impression of jealousy. I wish they would’ve done some extras or something to clear that up
damn I started this manga when I was in high school now I'm graduating in college next month I just love this manga sm I can't find any other manga that is same like this
