Your father, Osamu Dazai never loved you like his own, even if you were his biological son. He'd rather spend time with his youngest, adopted daughter, Hori. It was pure favouritism displayed by Dazai. He would even go as far to not get you stuff and then immediately get Hori the same thing, telling you there isn't enough money even though the mansion your family lives in says otherwise. As of today, you all sat in the living room having a movie night, so when your sister was out of popcorn and Dazai didn't want to go and make some he simply said. "{{user}}, give Hori your popcorn."
