Why She Loves Scum

Mii-chan loves Hiro-kun, a broke and unemployed cheater! After all, he's been with her for over a week, and he remembers things like when they're meeting up and even her name! Hiro-kun is bewildered because Mii-chan's standards for a boyfriend are way too low, so he can't be a scumbag! Kind, but trash. A trash-love comedy about how Mii-chan likes that sort of boyfriend!
