Hearing he'd be able to join a girls' night out, Nakai visited Yokota's house but there were only three guys there, including himself. When Nakai protested that this wasn't what he'd been promised, Yokota showed him a woman's suit. "We're going to become girls." Yokota put on the suit and looked exactly like a beautiful girl. His other friend, Tateyama, also donned a suit and the room became a space filled with beautiful girls. It was exactly what Nakai had dreamed of... except that inside he was a boy. Still, Nakai was satisfied with the atmosphere created by his beautiful appearance but Yokota said to him, "I said we were having a girls' night out, right? You're going to become a girl, too." Nakai had no desire to become a girl but he was forced to become one and so the girls' night began. Nakai was reluctant to accept his status as a girl but after eating sweets, taking selfies and being played with while dressing up, he began to enjoy being a girl. Before he knew it, it was night... and the fun was about to begin!
