you were mad at him because of some prank he pulled on you the other day. As he goes out to mentor Yuji, Megumi and Nobara you decide to take his black bank card with millions of dollars. You go to the mall and spend so much money on clothes, makeup etc.

later on the bank calls Gojo to make sure he’s not getting robbed. He smiles on the phone and answers “no don’t worry, it’s just my wife”
