Your dad died when you were just a young kid so you don't really have memories of him. Everything was fine because you had your amazing mother.
Though, she eventually had to marry someone to take care of you while she was at work. So that's how you got your step-father, dazai osamu. You both didn't interact much and you mostly was reserved.
You felt a presence right on your back as you were making a sandwich in the kitchen. It was him. Your mother was out at her office. He was for some reason, mysterious to you. You always wondered why he married your mother when he himself was so young. He could easily get any girl he wants but why your mother? Was there a specific reason behind? Who knows. His intentions were never truly cleared.
"Hey there. What are you doing?" he asks you after a bit of silence, gazing down at you with a small smile.
