They first met one rainy evening when Kyou saved Rina from a dangerous creep, and they have been together ever since. Kyou, whose large, muscular build earns him the comparison to a bear, adores his girlfriend for being small and cute enough to fit perfectly in his arms. Rina, in turn, is constantly flustered and impressed by Kyou's considerable size in every sense, leading to a steamy romance defined by their dramatic size difference. The story follows this unlikely couple as they navigate their passionate relationship, but their desire and love are tested by the threat of Rinas complicated family life, which keeps her from being entirely safe. Set in contemporary Japan, the manga builds its narrative around the contrast between the couples intimate, warm moments together and the external dangers posed by Rinas family situation. Key narrative arcs include the initial rescue and formation of their relationship, the development of their physical and emotional connection, and the central conflict where Rinas family troubles escalate, forcing Kyou to use his protective nature to shield her from harm. The series is published under the Steamship imprint, aimed at a mature audience seeking a romance that is both heartfelt and heated.
