Who would Dazai will mostly get along with?

Disclaimer: Look, in my opinion, I see Dazai as straight and according to canon as possible, I am not here to argue with anyone, but please I don't want any gay ship answers, or Chuuya x Dazai

Anyways, I just want some headcannons or theory in which I wanna know what kind of woman Dazai would get along with and become friends with easily, or maybe fall in love or find persuasive in some way Like how would he react if he found a woman in both behavior and personality and outer appearance that blows his mind, she is perfect in everyway and gets along with everyone, I know that Dazai maybe low self esteem but she is someoe he can't let go because just of who he is, or what he thinks or feel, you know what I mean? What if it tingles him everytime he see her, and even if he thinks low o himself and that everything that is worth keeping will be taken away from him he still can't go of her? I honestly wanna know what he will do or react? I am writing a fanfic too though
