## Description
This is the debut work for Lovematic. 

Kureha Gakuen, also known as the ‘outdoor baths school’, was formed just last year by the merger of a boys’ school and a girls’ school. The school administration was concerned that the boys and girls were not getting along well, so they decided to create the ‘intergender relations normalization committee’. Kazuya was enlisted into the committee, along with his osananajimi Kaho, class rep Yukina and enthusiastic classmate Nanao, each of whom had a different view on the matter. He figured that since he didn’t have any experience with love relationships himself, it would be best to get closer to the girls.
