seme is divorced since Hinata was 1 year old, so Hinata doesn't recognise him much. Mom died in an accident, so he became a single dad.
he came to school looking like a gangster to the other children, so other kids kinda mock Hinata (the child). The kid is a chibi megane. He's quiet at first, but he can be cheerful just like any other kids.
uke used to be seme's classmate (had a crush on him too) and is the kid's homeroom teacher. He saw that seme sucks at taking care of his kids, so he helped.
long story short, they got tgt and lived happily. It's a heartwarming story <3
