i hope you write it!! i think there is not enough tsujimura fan art/fic in this fandom ;_; i've done my best to contribute to tsujimura nation but it's hard out there for a gaiden enjoyer. i do super agree that he really seems to have like. an interesting "soft" spot for her despite putting up a cold/harsh exterior? i think post-dark era ango really took dazai's "everything i want i lose" mini speech to heart, and i think he's actually been WORSE about avoiding close relationships with the people around him than dazai. like dazai keeps his distance from his peers too but i also think dazai is a natural extrovert (the fandom tends to disagree with me on this kjfgskjdf but idk i think dazai very clearly desires to be around people but punishes himself by avoiding them. born 2 extrovert forced 2 introvert etc etc) whereas i do think ango is more of a natural introvert already, so like between that and his enormous guilt over what happened in dark era, he's so so reticent to even appear approachable to his colleagues and subordinates i think. which just makes a potential relationship between ango and tsujimura even more spicy to me. tsujimura also has so much baggage and i think ango would be a really interesting person to help her unpack this too? especially with the way his ability works and whatnot. they're an interesting pair!
