Evelyn Dunn becomes pregnant before marriage and is bullied by her stepmother and stepsister. By chance, she becomes the assistant of business tycoon Alexander Young. Pressured by his grandfather to marry and have children, Alexander proposes a contract marriage, and the two begin living together as a fake couple—unaware that the baby Evelyn carries is actually his. As they face schemes and misunderstandings from rivals and family, they gradually fall in love, marry for real, and welcome triplets, while Evelyn also fulfills her dream as a jewelry designer.
