The second of the popular amateur involvement project last time! This time as well, I asked an amateur female college student to participate in a verification experiment to verify the question "Is there friendship between men and women?" Mayu-chan, who has a relationship with seniors and juniors in the same seminar, has black hair and eyes patchy, Natsuki-chan, who is a childhood friend at the same university, is cool with a black girl, and Aina-chan, who is a circle friend and classmates, grew up as a young lady.
