The second installment of the popular Amateur involvement project from last time! This time, we asked Amateur female college students to participate in an experiment to verify the question, "Is there friendship between men and women?" Mayu, a senior and junior in the same seminar, has black hair and big eyes, Natsuki, a childhood friend from the same university, is a cool black gal, and Aina, a classmate and club member, was raised as a rich girl.
