Every year, I went to a fireworks display with my best friend Rui and childhood friend Rima. At the fireworks festival we went to together again this year, Rima confessed to Rui, but she was dumped. She said, "I'm going home." To hide her tears, she left first with a smirk, but she became worried and chased after him. She finds Lima on the side of the road, soaked and heartbroken by a sudden downpour. The rain just keeps getting stronger, and she runs into a love hotel together. Wet from the rain, her yukata stuck to her skin and her bra was visible. A young man and a woman were alone, and it was inevitable that something strange would happen.
