Houkago x Ponytail

Natsuki, an otaku high-school girl who'd much rather spend her money on manga than pretty dresses, accidentally injures a creepy-looking mangaka, Kiritani Taichi. To repay him, she agrees to be his character model until he fully heals. But what's this? Kiritani-san appears to be hiding a secret from her? What will become of these two?
