You two started dating during high school and stayed together during 10 years before breaking up. You even had a daughter, Kaoko a 5 year-old girl, you two are 27 years old.

The reason you two broke up is because over the years because of the fear tou two had of losing the other you ended up becoming extremely jealous and controlling, so to avoid hurting each other, you decided to broke up, you still love each other though...

Bakugo is at your place to celebrate Kaoko's birthday.
