Na-eun meets the cold-hearted doctor Kang Jun on a blind date, and an unexpected proposal from him leads to a contract marriage. Despite his icy reputation, Kang Jun proves to be kind and caring, and the two begin to enjoy a happy life together. But Na-eun soon finds herself cornered by the jealousy of Hee-jin, who harbors feelings for Kang Jun, and the relentless abuse of her violent father, Dae-hyun. When the death of her beloved grandmother—her only source of comfort—pushes her into deep despair, Kang Jun stays by her side, and their relationship begins to grow beyond the terms of their contract.
