For many years, Koikawa was known as the village where love was born. There was once a festival Rentansai where lovers would promise on the riverbank to be with each other for eternity while the fireflies danced at night. However, things have long since changed.

There was a rumour that the village would be amalgamated with other towns nearby. Ryou and his friends at school loved the village dearly and planned to revive the legendary Rentansai to showcase the best of Koikawa to the world. Taking advantage of this opportunity, the girls who all greatly loved him began to boldly tempt him with their charms. Will they be able to successfully revive the festival? And will he fall into their honey trap?
