I just read chapter 79 and... wow

I still don't know what to think about JJT, or the story in general. Maybe it's because I read 70 chapters in less than a week, but I felt that the change from a normal guy to a complete psychopath was very abrupt. However, it makes sense, although I'm not sure if I like him as the MC. I also don't know exactly where the story is going with the characters from the fighting class 2. Maybe in the future they will stop those from class 3. But I was quite impressed by how dark the manhwa became. It's difficult to read a manhwa like that nowadays.

What do you think about JJT?
