Sakuta wakes up and continues his life as usual; going to high school, studying for university, working, and dating Mai.

They assume it is a new Puberty Syndrome case, with Futaba asking him to consult young Shoko Makinohara as she knows of multiple realities, but they leave it for the time being.

Sakuta realizes that this is not the life he needs, so he has one last pleasant call with his mother before asking young Mai to take him back to his original timeline.

Back in his timeline, Sakuta notices his journal has a message reading to get a grip on his life, put a letter into Mai's mailbox, and figure out his relationship with someone named Touko Kirishima.

The project was initially announced during the Aniplex Online Fest event in September 2022, alongside its predecessor Rascal Does Not Dream of a Sister Venturing Out.
