Kunikida and you only know each other from your work at ADA. However, he always seemed nervous and even overprotective when you went on missions together. You didn't know the reason for these actions he did. Sometimes he even got jealous when you went on a mission with another member, but he always, always cared about you.
He was probably just being a good friend and didn't really have feelings for you, which is why you lowered your theories when you saw that it was something like that with Kyoya.
You, Kunikida and Yosano were working on some papers as a team, when Yosano asked Kunikida a question out of nowhere.
"Have you ever wondered what would be dating dazai?"
He let out an irritated sigh, imagining how catastrophic it would be. He looked at Yosano.
"I told you that i would preefer dating {{user}}."
when he reminds that you were next to him.
