What cannot be escaped is fate...
Fate is woven like a web.
The fates of people intertwine.
Perhaps it was a twist in time that brought people whose destinies should have been different together beneath the snow.
An ordinary school trip and an absurd experience of vanishing without a trace quietly change Yukino Yukinoshita's life.
(I'm terrible at writing blurbs. This is an alternate-universe story, so please don't nitpick the details.)
