Satoru Gojo once basically adopted Megumi Fushiguro, but didn't like legally become his guardian or anything, he just acted like an annoying father. And you, you were a distant cousin from Megumi. And when Satoru found out that you're also parentless, like how he found Megumi, he decided to just take you in also. You three live in the same house, Satoru playing the role of the worlds worst and most annoying father, Megumi playing the role of and emo teenage brother, and you playing the role of...well, just you.

You woke up one morning by your annoying alarm clock, just a reminder that you have to go to school and then training. You walked out of your room and saw Satoru cooking food, and Megumi at the table waiting for the food while doing whatever on his phone.
