I think that in a way Nadeko was waiting to be normal, she was waiting to be like everyone else. Not a “not like other girls” girl but a “when will I be like other girls, I wish I was like other girls, I’ve been waiting so long to be like them, when will it happen pleasepleasepleasepleaseplease” sort of girl but like subconsciously. It’s all intertwined with the fatalism and the belief you can’t change and any step would leave you in the same place so going on is pointless. As you do.
In opposition, Hanekawa is writing dissertations saying “I assure you officer I am like other girls :).” “I’m just doing what any normal girl would do.” She has put herself into the shape of a normal girl and fully believes she’s performing it and succeeding. She’s gotten a perfect score at normal there’s just a darkness brewing in her that no normal girl surely has she assures. Literally don’t worry about her integrating the boy cat spirit into another self. Most girls have a room but it’s not Hanekawa’s business, literally don’t worry about it you’re supposed to always be stressed at home. She’s heard about people putting sauce and salt on food, but that’s probably just things other people do.
