Bungo: Yokohama's Number One Novelist, Sooner or Later!

[Bungo Stray Dogs fanfiction + short story + romance + OOC warning + immature writing style, free-flowing, slice-of-life plot, the protagonist will not be part of the original story, it's a fanfiction with many original characters, please don't read if you mind, and you can get the general style from the synopsis] Self-introduction: I am an assassin. After all, in a dangerous world overflowing with superpowers and guns, isn't it normal to be an assassin? By the way, my performance is 100%, and I still have the professional ethics of an assassin. I can't call myself the number one assassin, but I can barely be the number two? After all, my main job can't support my living expenses, so I can only occasionally do side jobs to maintain my precarious life. Serious synopsis: Me (without blushing or skipping a beat): "I'm a law-abiding citizen." "..." Would a normal person introduce themselves like that? After several years of assassin experience, I unexpectedly joined the Armed Detective Agency after a day trip to the military and police, becoming a member. It feels good, except my wallet hurts. Everyone: "Isn't this your own fault?" I can't refute it: I'm overwhelmed with sadness. Later, the conspiracy known as "The Book" fell on my head. I'm so annoyed: I've already told you I have nothing to do with the book, but you just won't believe me. Thumbs up, six. And then… I can't spoil any more!!! Attention!!! This isn't a fictional story; the main character is female. CP: Hmm, forget it, I'm too incompetent to write romance. (Originally it was Dazai.) Let's go with a friendship story. Also, proceed with caution before jumping in.
