Mahoro knows exactly when she stops existing, and she spends every remaining day making Suguru's life normal instead of fixing her own. The show builds comedy around domestic chaos, then pulls the floor out by reminding you that every perfect moment is borrowed time. It doesn't drown in melancholy, it chooses tenderness instead, making the countdown feel less like tragedy and more like the only honest way to love someone temporary.

Mahoro's days are numbered. As her bond with Suguru and his classmates grows closer, the count of days left before she shuts down keeps shrinking. Then a second android girl comes into their lives and quickly becomes attached to Mahoro. This sci-fi romance mixes comedy, drama and ecchi humor with the steady approach of that deadline.
