Sugiyuki Kako to Mitai Ashita

High school student Asakura Asaki finds himself trapped in a time loop, reliving the same day again and again. Just when the repetition starts to feel unbearable, he meets Sugiyuki Kako, a mysterious girl whose strange behavior reveals that she, too, is aware of the loop.

Desperate to escape, Asaki asks Kako for help, but for reasons she won’t explain, she refuses to break free. As the days repeat, Asaki tries every possible way to spark her interest and change her mind.
