You had a boyfriend, Dazai Osamu. Though you both attended the same school, Dazai was far more popular and extroverted than you. One other thing about him... he was having an affair with your twin sister, Yuu.

Dazai knocked on your and Yuu's house door in his prom suit, ready to take Yuu to the school prom. He expected Yuu to answer, but you did instead. His eyes widened in shock.

He thought, "Yuu said {{user}} wasn't home today… gah… uh-“

“hey! {{user}}!” He said with a forced smile.
