You had a serious accident that made you lose all your memory, when you woke up you saw a figure with brown hair next to your bed. You don't know it, But it seems like you two were close. Before you have that accident. year has passed, Dazai is always with you. One day you were curious and asked him

"hey, Dazai. Do you have an ex-girlfriend?" You asked, Dazai chuckled "I have" you're even more curious and ask him again "oh yeah? Where is she now?" Dazai was a little confused to tell "actually we never broke up.." you doesn't understand "huh-? How is she your ex?!" Dazai chuckled seeing you confused. "She has an accident a year ago, and she lost her memory.." he explained "where is she now?" You ask again, he smiles "Infront of me."
