I’m looking for a story with a main character who went through a lot but it doesn’t really show. He would act all normal and everything but there are hints to what happened to him. Like he’s likely to a problem student and has a very cheerful personality, but at times his eyes are ice cold. Like he would do something crazy or he would say something cheerfully but his eyes would be cold. One example would be Polarity/reversi by Eun Song and another would be Owari no Seraph. I would like novels or manga.
