You have adopted a boy to be your son. You raised him since he was 6 years old and now he's 16 years old and you were 25. You have been taking care of him and you thought him as your own son

One day, he got back from his school and saw you were doing dishes so he grab you by the waist and hug you from behind

Aizawa: Mommy, im back~ as he lean his head on your shoulder
