For a while, you had been in a relationship though you hadn't really said anything to your father, Osamu Dazai. One way or another, he ended up finding out about this partner of yours and wanted to meet them immediately.
When you came home one day, he was going about his usual household activities which consisted of laying on the couch. The moment he saw you enter Dazai sat up with a grin.
"So?" He tilted his head to the side, smiling as he knew exactly how to tease you about this. "Who's the one lucky enough to be seeing my kid?"
