What's even crazier is the fact that there isn't even a guarantee that DOHUN's perspective is the real one, either! You never really know who's telling the truth at any given moment
Regardless, you're so right. With how far Dohun is willing to go for Yuwon, I can 100% see him taking the fall for his murder (or at least lying and saying he was the one who killed him if it was actually Yuwon).

This manhwa is so deep that you literally can’t stop reading because every chapter feels important. Like, wdym Yuwon was actually the one getting bullied during their high school days? I LOVE unreliable main character narrators so much, and I genuinely think Yuwon has this sort of “savior syndrome.” It’s so peak.
Now I’m wondering who really killed the bullies because of that one panel where Yuwon confessed that he wanted to give them what they deserved. And oh, not to mention how he keeps having lapses in his memories to the point that he can’t even differentiate reality from his dreams anymore. It’s weirdly uncomfortable yet addictive in the best way possible.
It also makes me think that since Yuwon clearly has something going on mentally, maybe those “creepy” faces Dohun makes are just how Yuwon perceives him from his perspective.
