Tianmen City, located in the tropics, experienced a once-in-a-millennium snowfall in winter. At that time, a college student named Bai Yifei accidentally made contact with a girl from another world during an emotional breakdown. "Huh? I think I just saw a different kind of scenery. I must be too tired... probably."
On the other side, in another world called the Suwell Continent, snow in the sky glowed an unusual silver. A dead girl was awakened once more. Her memories had been reset, and she had lost all memory of the life before she was reborn. In the snow, the girl opened her eyes. "Who am I? Where am I? Why am I here?"
Two people who had never met, living in different worlds, embarked on entirely different stories. An invisible thread bound them together.
