My Ruined Enemy Belongs To Me Now

Synopsis

I took my unlucky rival, Carter Murray, home. Then, I made him do all sorts of chores for me every single day. Not only did he have to do the chores, looking all pitiful, but I also teased him whenever I felt like it. Watching Carter clench his jaw in embarrassment and anger, it was just way too satisfying for me. But then, one day, I suddenly learned the truth. It turned out Carter's family never went bankrupt at all. Was he just pretending to be broke the whole time?
