Modern office worker Su Wan accidentally transmigrates into another era. Faced with an unfamiliar time and her cold “husband,” Xiao Jinyan, she gradually adapts to her new life, moving beyond her initial panic and helplessness.
She uses her modern know-how to improve their meals and resolve disputes with the neighbors. As they spend time together, she also glimpses the tenderness beneath Xiao Jinyan's steely exterior. They go from the awkwardness of living in separate rooms to facing family chores and the tides of a changing era side by side, and affection slowly blossoms between them.
From striving in the workplace and raising children to disaster relief during a flood and growing old together, Su Wan and Xiao Jinyan turn their bond across time into a decades-spanning love story, built on devotion and steadfast love.
