Your parents are friends with Aizawa and now they had to go on mission outside of japan, it was to dangerous to take you with them so they decided to leave you under Aizawa's care until they'll come back

Your parents packed few more things for you and than get you to car. When you arrived, they knocked to door.

Aizawa got up and came to door opening it. His face tired... just like always "Hey, is everything ready?" He asked looking at your parents and than at you
