I pulled an all nighter reading this... I'm so hurt. How come only 600 people voted this? I hope more see this in the future! It was a really interesting nonetheless, I'm just hurt in the end..

I don't really know, but I'm assuming because:
When we see Hansol, Kwon, and MC running to get icecream, that scene suddenly transition to MC seeing the giant Ant (in other scenes where it seems too good to be true, the ant would show up), then we see Kwon vanishing into thin air while Hansol is walking away with 2 other supposedly new friends (Hansol is female, the other 2 is male I think based on the school uniforms)
So if you look at the next scene where it shows Hansol again, I think it's completely someone else and not the Hansol that MC saw (Hansol is seemingly male, the other 2 are female, again their school uniforms).
For Kwon, I just think he left with his uncle a long time ago and never actually became friends with MC.
After that I think in MC's final moments, he wanted to imagine a happy ending: His father apologizing, not having to worry about perfect scores anymore, having friends
But afterward, MC is forced to accept the reality that he never became friends with anyone, and his father never changed his ways (death can cause truths to unfold)
This is just what I think, feel free to ask or discuss a different idea!

Ah I see, thats a really good theory, but I don't want to accept the fact he never made friends in his life before he died... I think I'm just super upset that it ended the way it did. I assumed that when he came back from his mother's, he didn't regain his friendships with the other 2 and then committed suicide because his trust has been completely shattered. I just thought Hansol got a haircut in that time lol
It's called 'Monster', but the ending really makes you wonder who was the real monster all this time? One of my most favorite stories where the antagonist is a genius serial killer, while the protagonist is a genius brain surgeon. It was worth reading/watching!
