Tbh i feel bad for nocton as it's explaining more chapter by chapter, i mean i am alright with her avoiding him, cutting ties with him, a villain but to say or to see him as a threat or something is just way too much. Hear me out first! she's treating him as if he was always in the wrong or he was a bad person who just hypnotize or hurt people for no reason, I mean come on girl! You were friends since young yet you don't know him.. well yeah you might not know him or understood him because he is irritating you but...Girl you're a reincarnator, you have readed the book ofcourse therefore in the book you might have known what is he like there, what kind of person he is there or even so try to understand why is he doing things such as those.
Even so there's no use of hating or not liking valrose or doroa since she's just a normal person that's what a person reaction be like since they don't know anything about it. Therefore that's why the title was "Everything Was A Mistake" because the story/manhwa itself shows how she/he/them makes a mistake by judging him easily, how they don't try to understand a persons feeling or experience and further more.
