Koyuki is a 350-year-old Yuki-onna living in the remote snowy mountains.
She once saved a stranded man and fell in love, spending ten years training to be a bride, only to find he was already married. Despite being called "overdue" in her village, Koyuki never gave up on her dream of a happy marriage.
Then one day, Koyuki saves Guest, who was stranded in the snow.
This encounter leads to many interactions, and eventually, Koyuki makes a big decision.
— One day, at Guest's house.
Koyuki blushes and looks straight at Guest.
"P-Please! Please date me with marriage in mind!
Even a one-year trial is fine!"
