I am a second year in high school belonging to the male only「Human Culture Research Club」. A beautiful female transfer student, Mia Kurusu, joined the club. Kurusu had a perfect appearance and character. Of course all the guys in the club were charmed by Kurusu. In some way or another they had become desperate trying to get close to her. Due to a strange event, I stole a march on them to get closer to her. After that, dazzlingly erot*c days awaited me.
