Please Don't Mess with Me, Nakase-Kun

Nana Hachioji has had a pretty hard life. Constant bullying and harassment from her piers has caused her to close herself off and become a shut-in. However, when a a young underclassman with a flirty attitude and a short size to boot, alongside his friends, confront the poor girl, things start to change in her life. For better... or Worse. Depends on how long she tolerates him for.
