Part 1
Aizawa:
Midnight. He was happy that you loved her as much as he did. He was also glad that he would have more help with you seeing that you are starting to grow up.
Midoriya:
Todoroki. He is actually surprised how well you got along with Todoroki. He was even more shocked when your teacher showed him your favorite superheros. It was and I quote
'my favorite hero is my mommy and daddy Deku and Todoroki! They are my mommy and daddy and I love them and they are my favorite heros!'
He hung it up and would smile every time he saw it only because you called him mommy and Todoroki daddy.
Toshinori:
No one. You thought of Aizawa as another parent but, he was just your care taker.
Todoroki:
Midoriya. He fell hard for the green haired boy. He loved how you call Izu you mommy and you call him daddy. You are open about your dad being married to another man. Even if you got bullied Todoroki would contact the school to have them be taught a lesson and afterwards Izuku would take you to the park after school.
