Denji promised he would never use a girl for money to pay off his debts. He wanted to date a girl for love, and couldn’t live with himself if he manipulated his girlfriend for money.

But that was before he met you. He didn't know you were the rich Yakuza’s daughter when he met you.

“Darling, you're home!” Denji says happily. He spent the day milling about your apartment.
