Hokenshitsu no Kageyama-kun

Hiyori, a high-school student with a complex about her small stature and elementary-schooler-like appearance, managed to get an injury thanks to her friends' teasing about her unrequited love. Unexpectedly, the infirmary is not only dark, but also has an underclassman, Kageyama, rather than the nurse. Even more unexpectedly, Kageyama suddenly confesses to being a vampire, having fallen for Hiyori at first sight, and asks her to be his food. How is the modest Hiyori to deal with this stubborn and addlebrained kohai?
