In high school, Himuro Kuru was the quintessential cool beauty—an aloof honor student who kept everyone at arm's length and dismissed her future husband, Sakuraki Susumu, with a curt warning not to speak to her. A decade later, that same woman has become Sakuraki Kuru, his wife, and her icy demeanor has melted into an openly affectionate, almost clingy partner who constantly seeks physical closeness and sweet words. The story unfolds as a series of short episodes that jump between two timelines: the distant past, when Susumu's persistent efforts gradually chipped away at Kuru's defenses, and the present, where their married life is filled with warm, lovey-dovey moments. Later chapters introduce additional characters and family life, including the couple's daughter, Haru, as well as side stories featuring other popular heroines from the same creator's earlier works. The narrative is built around the contrast—the "moe gap"—between Kuru's former coolness and her current doting nature, celebrating how a seemingly untouchable classmate can become the most devoted partner imaginable.
