Chloe, an ordinary young woman, enters a one-year contract marriage with Julian, CEO of Vance Group, who is pressured by his family to marry. She needs money for her grandmother’s surgery. Due to a mix-up at their marriage registration, they never truly see or know each other. When the year ends, complications prevent their divorce. Chloe then accidentally joins Vance Group as Julian’s executive assistant. As they grow closer, both develop feelings—but each believes the other is already married. Meanwhile, Valerie, a design director in love with Julian, conspires with greedy Roxy, who pretends to be the real Mrs. Vance, to sabotage Chloe and seize the family fortune. Through workplace traps and an identity scam, the “stranger spouses” must uncover each other’s hidden identities, survive crises, and find love and redemption.
