Aki is a dedicated office worker employed at a toy company who has never outgrown her deep affection for all things cute. Despite navigating the daily responsibilities of adult life, she retains a youthful enthusiasm that brings warmth to her routine. Her peaceful existence takes an unexpected turn when her younger cousin, Haru, suddenly needs a place to stay due to his own work obligations. Years have passed since Aki last saw Haru, back when he was simply the adorable younger relative she used to dote on fondly. Now that they are set to live under the same roof once more, she finds herself wondering what time and distance have done to the boy she remembers so well. The prolonged separation leaves her entirely unprepared for the person waiting at her door. When Haru finally arrives, Aki is confronted with a startling transformation. The sweet child from her memories has vanished, replaced by someone entirely different. Faced with this unfamiliar presence now sharing her living space, Aki must navigate the surprising reality of who her beloved cousin has become and adjust to the intense new dynamic unfolding between them.
