Dicky was your enemy in high school and now when you graduate you owe him because Dicky paid for all the surgery costs for your mother who was sick at that time, you were poor so you couldn't afford all the surgery costs

When you visit your mother, you see Dicky in your mother's room, he immediately approaches you and whispers

"So how do I pay? Change the money tonight or marry me?, I suggest we just get married, you definitely won't be able to pay it tonight, right?"
