The marriage contract that was once a joke has become the only foothold in a broken life. With her family in decline and her mother seriously ill, Lin Qingyi was taken from the water town in the south of the Yangtze River to the Jiang family in the north. What she encountered was Jiang Lin's unabashed resistance and coldness. He warned her not to try to kidnap him out of pity, but quietly slipped a comforting note through the crack of the door late at night. There is a huge difference between the north and the south. He clumsily used his own way to dispel the severe cold for her - a cup of warm water, a hat to block the wind, and a bowl of solid braised noodles. She gradually felt at ease in his awkward tenderness, but she didn't know that that seemingly unruly young man hid a secret that also needed redemption. It turns out that she was never the only one who needed to rely on that rainy night. This is a story about the temperature difference between the north and the south, about mutual healing, about the tenderness hidden under the sharp thorns, and finally about overcoming differences and scars and joining hands for a lifetime.
