Mankitsu Shitai Jouren-san

Izumi, a university student part-timing at a manga cafe, got curious about a regular customer. Her name is Honami, a high school girl who comes to the manga cafe regularly, and he can't take his eyes off her. But this seemingly cute and innocent girl has a secret...!?

A slightly naughty but pure romantic comedy where a gentle couple will get to "enjoy" their youth to the fullest!!
