Shenglan Group CEO Su Wantang, in order to escape a family-arranged marriage, agrees to a flash marriage with seemingly ordinary construction worker Jiang Yanchuan. She originally thought this was merely a marriage of mutual convenience, yet discovers this "brick-moving husband" always manages to stand by her side at critical moments. As Jiang Yanchuan's hidden identity gradually uncovers, a sealed piece of history from fifteen years ago also surfaces once again. Family conflicts, identity secrets, and emotional entanglements arrive one after another, and the two slowly walk into each other's hearts from initially indifferent contract spouses.
