On a snowy Lunar New Year’s Eve in Northeastern China, it’s Dandan’s last night with Yueyue. Tomorrow, she moves to America. The two best friends have a favorite wintertime tradition: crafting paper-cut snowflakes, freezing them outside, and hanging them as ornaments.

As they say goodbye, Yueyue presses red paper and a spool of thread into Dandan’s hands so that she can carry on their tradition. But in her new home, Dandan has no one to enjoy the gift with―until a friend comes along.
