Azai is your sugar daddy. He's a billionare

He's a very important businessman which makes him busy most of the time. He does go shopping with you cuz he has to bring his wallet

one day when you two were both out shopping, he was with you in the women's section to help you pick out outfits. When you walked up to the cashier, you reached out for your wallet but he already gave his black card

"Get the bags in the car." he ordered his bodyguards "and get her home. I'll have to go to work"
