Four virgin friends who aren't popular decided to celebrate their friend Taro's birthday. Complaining about their lack of luck with women, they went to buy alcohol and found a drunk woman passed out. The woman, Ayaka, was tipsy and excited, so she ended up going back to the guys' house. In this situation, all four were still virgins, so when she said, 'How about I help you lose your virginity?' the guys decided to give it up.
