Synopsis
Karada Iokawa, a lively and dependable girl on the cusp of junior high, detests being seen as immature. Following the loss of her parents, her overseas-studying elder brother Hiro comes back to look after her. Accompanying Hiro is his former girlfriend, the poised yet sporadically childlike and headstrong Shouko Nogami, who seeks to understand why he left her. Tensions rise between the two young women, leading to a confrontation where Shouko labels Karada as childish. In a bid to mature, Karada makes a wish at a shrine, unknowingly activating the shrine’s magical wishing stone. As Karada grows older, Shouko, who was coincidentally close by, regresses into a child. Now with their ages reversed, Shouko and Karada must navigate their new roles and work towards mutual understanding and personal growth.
