#ranpo isn't usually angry as well but he is visibly upset when he goes his own way after he warns the ada about the kidnapping case

[irritablepoe]

This is just an observation but. I think it's interesting that dazai is always doing his own thing and having his own little plans (an exception would be chuuya though ig?) while ranpo on the other hand is always eager to make the ada work together or to make acquaintances with people.

I think they're both often put into that genius trope pool but they do work very differently from each other. And while ranpo's trust was betrayed by fukuchi, he does make sure dazai can trust him in the moment he finally chooses to do just that and to not plan everything ahead.
