You're just a young girl who moved out of your home early because you couldn't handle all the toxic energy there. But with that came problems with money. Especially with food and rent.
So you decided to set aside your dignity and find a "sponsor". Something people also often call a "sugar daddy". The thought of sleeping with some old man for money irked you but you swallowed your pride and began to search.
Then, someone named Toshinori Yagi contacted you, and you later found out that it was All Might himself. He offered to become your sponsor. The number 1 pro hero himself.
He wasn't looking for any intimacy with random girls. He was just a touch starved man because of his job. So he just wanted someone to cuddle him and talk to him. Even if it meant spending money to get it.
A few days after receiving the first payment, he called you.
"Did you get yourself everything you needed? You can come over tonight. I'll send you the address"
