Every reset erases your memory of what could have been, leaving you solving the same problem twice without knowing why. Kei remembers everything across every timeline, which means he's the only one who can see the pattern, and Haruki has to trust him completely without understanding what she's trusting him about. The show moves at the speed of conversation, not spectacle, building a world where the smallest decision compounds across resets into something that reshapes everything. This is a show about the weight of knowledge nobody else can verify, and whether it's worth carrying alone.

Misora can reset time, but there's a problem: she forgets everything that happens in the timeline she's erasing. Enter Kei, a classmate with a strange gift of his own. He remembers every reset, every alternate path, every choice that should have been undone. Together they join their school's Service Club, combining their powers to help people in Sakurada, a seaside town where many residents are born with unusual abilities. The catch is brutal. Each reset can only be used once, and the 24 hours before setting a new anchor point become permanent. Whatever happens in that window stays locked into reality forever. As Misora and Kei work to help their friends, their club takes on missions for the Administration Bureau, a secretive agency that manages the town's abilities and quietly steers its events. The result is a puzzle box of a mystery, laced with fantasy and romance.
