I can understand that panel where he looked at him with a type of hatred of disgust. He did kinda rape him in a way but he still hold some good memories with him.
I don't know if this will help, but as far as I understand, the Mugos (personalities) were created when Muhan was tortured to turn him into a god. The Gluttonous personality is because he was starved and given raw food. The Reader personality is the most proud, like a "god," but I also think it has to do with the fact that Muhan was a nobleman and a student before he died. The third personality is the most unique, but I think it resembles Muhan a bit, perhaps a more "mature" and solitary Muhan. This is just what I think so far (⊙…⊙ )
Can anyone explain why MC looks at Lee muhan with so much hatred but still looks like he cares abt him at the same time (in the flashback at least). Is he only looking at him like that because he’s a sol and he hates sols? And also how is Lee muhan even remotely related to the mugos? I’m lowk dumb so idk if this is stuff we’re about to find out or should already know…
