Huh, so I got that one right. Jeongtae being a former monster gains credibility after this chapter… and maybe Yun-yeong?
Curious about the psycho teacher now.
I thought Yun-yeong might be, but it doesn't make as much sense as I thought at first. They don't seem to turn into a copy of someone they ate, so she wouldn't match any of the students in the class. So instead of her being the only survivor, they would have a full class of dead students and 1 new person that appeared in the room with them.
So I think her situation is more complicated than that. Especially with the mirror entity, there's nothing else like that for us to compare it to, so there must be completely unknown factors at play.
Now it's possible that she DID appear as a copy in the classroom, but it was because of shit we don't know about (probably connected to the mirror entity) and isn't the norm.
I'm also curious about the teacher. Do we know literally anything about her? I can't remember.
