Amid the mists and rain of the Republican era, the Fu residence is a warm haven, sheltering the intertwined feelings and growth of several people. Tongjia Wantang and Fu Zhenbang are bound by a marriage contract. From their initial, distant courtesy, they gradually come to understand one another as they share their daily lives, nurturing a steady, lasting love through understanding and acceptance. They become each other's support in a chaotic age.
Shen Qinghe, carrying the wounds of her past, seeks refuge at the Fu residence under the title of “concubine.” But through her letters with Lin Yan and their discussions of books, she finds the warmth of a kindred spirit she had long thought lost. Once Lin Yan learns of the pain she has buried deep inside, he shields her with quiet companionship in the rainy lanes and patient support in everyday life, finally dispelling the gloom in her heart. Books bring them together, and beneath the moon, they pledge their love.
Su Yusheng yearns passionately for a career in show business. A talent scout unexpectedly spots her, but Fu Zhenbang objects out of concern. Fortunately, her close friend Yu Jinghong secretly helps get her work seen, while Tongjia Wantang gently puts in a good word for her, and she eventually gets his blessing. She faces hardships on set and shines through sheer resilience. As her career takes off, she still has her sisters' deep affection to fall back on.
In the Fu residence courtyard, peach blossoms mingle with the shadows of archery, and moonlight falls on those returning home. At one family banquet after another, and through the hardships they face together, everyone sheds their barriers and becomes a family with no blood ties, yet closer than kin. In the end, Tongjia and Fu are devoted to each other, Lin and Shen walk side by side, Su Yusheng's career flourishes, and Yu Jinghong sees her dearest friend safe and sound. Amid the shifting fortunes of a turbulent age, the Fu residence makes love its soil, allowing warmth to take root and every heartfelt wish to find its fulfillment, composing a long, tender song of the Republican era.
