A debtor is someone obligated to make a specific payment to a particular person. Y-chan, unfortunately, became collateral for a debt due to a bad "parent lottery" (meaning her parents failed to provide her with a good upbringing). I wanted to help her out, but her arrogant attitude made me decide to show her the ways of the adult world. I had my way with her, spitting all over her, and now I'm thinking about taking her to a sex club.
