Chị kế nhỏ trả nợ cho người anh kế lớn tuổi của cô ấy bằng một cuộc đụ giàu có.

My shy stepsister had her weekly allowance money taken away as punishment, so she doesn't have money to cover her school expenses. I lend her money and it's time to pay me that money, I collect it from her and she doesn't have the money to do it, so she pays me in kind.
