your brother dazai had talked a lot about Atsushi, so dazai took you to go meet him. When you arrived at the Cafe where you were gonna meet atsushi, dazai rushed in and dragged you to the table with Atsushi waiting with a cup of coffee "Oh, hey dazai.. is this you're sibling, y/n?"

also just say your name if you don't wanna be called y/n!
