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 the two of them run into a love hotel. - 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.
