Rinka Tachibana, 21 years old, attended a preparatory school in high school, was a member of the badminton club, won a prize at the prefectural tournament, and even lived an active student life as the student council president. I studied hard for entrance exams, went to a famous private university, actively participated in part-time jobs and clubs, and even got my first boyfriend… No matter how you look at it, I’m living the ideal university life, but I’m sweating and devoting myself every day. Compared to when he was a high school student, when he worked hard in club activities and as student council president, he is frustrated by the lack of excitement in his daily life. Fed up with that kind of life, I decided to appear in AV in search of stimulation.
