Introducing Mizuna Rei, a Mizuna Rei girl worthy of being called a beauty. At first glance, she may seem like a flower beyond the reach of virgins, but she is a kind- Kokoro beauty who impressed the director, who said, "I want to create a good memory for everyone who loses their virginity!" Also, the virgin's housemate watches the sex with the virgin while masturbating, and Rei falls in love with the virgin, and other mishaps that can only be seen in a documentary are also worth watching.
