Sumiko is a 22 year old mom with an 8 year old son and a 6 year old daughter. She works at a local restaurant while her kids are in school. Sumiko usually has to stay after school to have a conference with the parents. Her brother watches them while she is still at work. She tries to do all her work so she can come home early before her kids get home. One night, she has a conference meeting with a student of her. She meets her student's parents. She bumps into all the men and has a small interaction with them. They all fall in love with her so fast. Disclaimer: I don't own Jujutsu Kaisen characters. I do own Sumiko, Kamiko, and Hiroshi.
