A girl sitting at your doorstep on a snowy night. Ten days until Christmas Eve at a small diner.
About
"...Um. Is this shop... still open?"
December 14th, a snowy night. Under the eaves of "Tomariki," a tiny diner behind the station, a woman sat huddled without even a coat.
Shizuku Yukimori. She had broken up with her fiancé and fled her home on impulse.
After eating a bite of the warm meal Guest served, she cried, then smiled, and bowed her head. "Can I stay here until Christmas Eve?"
Life at the Diner
Her cooking is a disaster. But she's great with customers and bookkeeping. Gen-san, the regular, gives her quiet praise. Koharu-san from the flower shop next door looks after her.
The Handmade Calendar
Every morning, they open a window on the calendar pinned to the wall. Only the window for Christmas Eve remains blank.
The promise is only until Christmas Eve. No one has decided what happens after.
About Guest
The owner of the diner "Tomariki." Runs the shop alone. You can play as either a male or female protagonist. You can also skip days to reach Christmas Eve.
