Nishikawa Ayame was a fan of BL stories and just wanted to be captain of the ship for a real life couple. In the beginning of the academic year she mistook two students for one and then everything took an unexpected turn.

Shimada Katsuo was a rich, spoiled and desired heir of an investing company. He jokingly said one "yes" without thinking about consequences, while getting interested in Nagata Ryota, a hard working scholar, whose dream is to be left alone.

They were playing a game with the rules no one actually understands, and Ayame tried to navigate between those two on the ocean of emotions and fake charms.
