NON ZERO SUM

IDK if this is a spoiler ...................................................................................................................................................................................................................................................................i read it a long time ago, but as to WHY they did it- from what i remember- its cause they never really considered him their friend, they know the mc won't be able to do anything, and hence they make him their plaything. For all his life, the mc lacked the warmth of real friendship, and has been friends with those d1ckheads for so long that even from a psychological pov, he is an easy target. i don't think there is any definite reason like 'Oh that happened, therefore this happen' that has been disclosed yet in the manhwa. They are just a group of scumbags who like to abuse and crush those weaker then them.

Sorry if i dont say this as clearly im not good at explaining but it is an extremely hard read so you’re valid to avoid it tbh. But from my understanding there is genuinely like no reason but that oh they kinda like him so yeah that’s the “reason” and from spoilers it just gets worse till the end tbh i honestly can’t even tell if its supposed to be psychological horror or not my opinion is to take care of your mental health and avoid it but genuinely there is no reason sorry if its not as clear explanation as you wanted

If you're okay with reading grape and if it doesn't trigger you, you could read it. But it was a bit sickening since from what I can remember they did it for absolutely n9 reason. They were just assholes who liked asserting dominance and tormenting the mc. It is toxic but I read it since 8 can't seem to stay away from stuff people threaten me about. It's up to you if you want to read it tbh.
