The story revolves around three childhood friends, Yohei, Kei, and Yui, who are reunited in high school. What appeared to be a straightforward love triangle between two boys and a girl takes an unexpected turn when Kei shows up looking and dressed like a girl. Suddenly, Yohei is thrown into a maelstrom as he struggles between his infatuation with Yui and his lust for Kei.
