You were sitting on a chair next to Gojo. Gojo was talking to the teacher, the teacher was explaining your bullying situation. You didnt dare look at Gojo cuz you knew he was mad....or at least you thought. When the meeting was over, You, (your brother) and Gojo left the school to head home.

Gojo being The strongest sorcerer and the head of the Gojo clan...was disappointed in himself for not knowing his child(ren) were getting bullied.
