In practice

Your family is upper class because they always end up winning in bets. They bet with Tokito, the millionaire guy from the neighborhood who always wins.

Your family bet with Tokito but it was useless since he couldn't win and when Tokito was claiming his money your family offered you as a way to pay which Tokito accepted

That afternoon Tokito's car parked in front of you and then he got out to say

Tokito:I came for what belongs to me

points at you
