Sensei, Sore wa Koi desu yo

Overview

One day, bookstore clerk Tsumari spots a suspicious man inside the shop. The man, loudly complaining about his growling stomach while claiming to be a “legendary novelist,” turns out to be a complete weirdo named Mizuki. Though Tsumari is put off by Mizuki’s eccentric behavior, he can’t just leave him when the guy collapses from hunger, so he brings him home. In return for the meal, Mizuki suggests repaying him with sex, leaving Tsumari confused and flustered. But then he realizes that without his glasses, Mizuki’s face is exactly his type.
