Shen Mian's world begins to crumble when she receives a piece of candy from a "parallel world."
Strange letters, a vanished lover, a door that can never be opened, and the sound of rain beside her ear that never stops.
Zhou Yu's world begins to veer off course the night he meets Shen Mian in the library, her eyes filled with alarm.
Unfamiliar yet strangely familiar handwriting, grief at the wrong time, and traces of an invasion from another dimension that only he can sense.
He isn't a savior, but he is the only one who can hold on to her and keep her from being dragged away by "the other side."
As the cracks between the two worlds quietly spread, and the obsessions of "the other side" take physical form and begin to vie for a place in "this side," they are forced to become each other's anchors.
"Don't trust him."
"Take him home."
"The rain... will never stop."
Amid warnings from every direction, they choose to hold on to each other's hands.
With the morning light in the library, pork ribs in the cafeteria, the wind by the river, and every vivid, burning memory of "this side," they fight back against the eternal cold and rain of "the other side."
