When his eyes get red, he doesn't has any control over his mind and body. It is like an instinct to get a body. Mr. Reaper explained it in the earlier episodes. Since our boy mc here needs organic energy that is full in humans and low in ghosts, that's why ghosts possess humans to get that energy. You can say that energy is like a dopamine or serotonin shot for the brain. Since our mc here is half human and half ghost, his body is in a constant need of that organic energy shot. And whenever he goes low for the energy, boom red eyes appear. But agreed how it feels like he is in own world with how everything around him is in chaos cuz of him. Prolly quite accepting of everything he is if I say. Like "oh this happened? So bad! But it is fine. It is alright."

I mean... He is just an extrovert. What can anyone do in that. If I were told I was going to die in few days, I did tell everyone about it before dying. Even make a will. Meet all my classmates and stuffs despite being an extreme introvert. Im saying this from my pov but Idk how you will react in that situation. Hm but you are right. In that sense. You just want mc to get a clear idea of how dangerous ppl would be if he lives his house. I'm sure he will come to understand this steadily considering it is Ker-nim's mc we are talking about. .
I kinda don't like how he's willing to like do it with anyone in his red eyed form yk? Like I had a hc that he was like that because of Mr.reaper (I mean the reaper is so garsh darn fine like I would die just to see him living is over rated anyway like GYATTT if we ever walked in the hotel and it said that one of us needs to get pregnant the two of us would come out and he will be the pregnant one) anyways what was I talking about oh yeah the main character he's idk he's kinda aloof is that the word for it?
