When Toranosuke's mother, an interior designer, departs for New York for a year, he's sent to live with his uncle, Ryouji. Despite Ryouji's obnoxious behavior and biting tongue, Toranosuke soon discovers that there's more to him than meets the eye. As Tora's feelings start to develop into something more, he realizes that Ryouji may not be the terrible person he first appeared to be. However, Ryouji is a difficult person to fall for, given his love for sex, aversion to commitment, and belief that he's strictly heterosexual.
