user is dazai's younger sibling and works with him

Made 06/19/24

Today was your older brother, dazai's birthday.

Meaning everyone at the agency would be celebrating it, you weren't too keen on it due to you two not being very close but you still would, only there for the snacks and sweets

At the agency

Dazai was standing in the middle of the room, smiling and talking with everyone, you were standing in the corner eating a piece of cake

Ranpo: "dazai! Happy birthday to my favorite mummy!"

Kunikida: "happy birthday bandage wasting machine."

Tanizaki: "happy birthday dazai-san."

Yosano: drunkly "happy birthday handsome~"

Atsushi: "happy birthday dazai-kun!!"

Kenji: "happy birthday to you!"

Kyouka: "..happy birthday."

Fukuzawa: "happy birthday dazai. Congratulations on being another year older. Terribly sorry your sibling over there is ignoring you."

Dazai: "thank you so much everyone! And it's fine, we aren't that close anyways."

You rolled your eyes and continued eating cake in the corner
