Southern girl Su Tangtang is deeply trapped in a low valley in her heart, and comes alone to the ice-and-snow-covered Northeast Xueling, where she fortunately meets the warm and simple-hearted family of Gao Cuihua who extend a helping hand. The Gu family uses warm food and sincere care to slowly melt the haze at the bottom of her heart, and the Husky Ersha also often keeps company by her side. Pilot Gu Huai returns home on leave, and gradually comes to know and cherish each other with Su Tangtang. Su Tangtang steps out of the pain of the past, regains the courage of life, learns southern traditional pastry-making craftsmanship, combines it with northeastern dietary characteristics, and founds her own pastry small business "Tang Li". With the companionship and support of the entire Gu family, she crosses the heavy trials on the road of entrepreneurship, and her career develops steadily.
