Sorry I meant to imply the rest of the chapters available until now, and that my impression was one trying to imagine the story as if I had only read this chapter.
Honestly, I think the girl is trying to de-escalate the drama, to "scare straight" the people around him....SO FAR, is not a violent yandere who tries to kill problems around our MC, like I guess "Mirai Nikki", which makes sense, since if people started dying left and right around him, he would be further traumatized, however writing it like that would also be the "easy way out" for an author I think, instead of planning things.
