Onna Tomodachi wa Tanomeba Igai to Yarasetekureru

Aoi Hazuki, the most beautiful girl in school, and Hisaya Minato, an ordinary high school freshman.

They live in the same apartment building and go to the same school.

They are such good friends that they go back and forth to each other's houses after school all the time.

One day, they were having fun playing together when Minato suddenly asks Hazuki to show him her underwear. Hazuki is reluctant at first, but Minato says, "It's not like you're my girlfriend, okay?" After that declaration, she begins to roll up her skirt. From that day on, Minato's "requests" escalate little by little, until finally......?

A naughty coming-of-age love comedy with the cutest girl in class.
