My Childhood Friend, Who Is the Most Popular Girl in the School, Is Too Cute and Naughty Only in Front of Me. I’m Doing My Best to Maintain My Sanity

Takamine Amane is an ordinary high school sophomore. He has one childhood friend. She is so beautiful that she is called the “Unattainable Flower” in the school. Her name is Saori Tachibana. She is a goddess with excellent grades, athleticism, and good-natured personality. But she becomes a super pervert only in front of her childhood friend Amane. Amane does his best to keep his rationality. This is a slightly naughty love comedy between two such people.
