The story centers around Stella, a woman who enters into a contract marriage with a powerful mafia boss named Callan Moretti. However, Callan is completely unaware of a massive secret: the assistant he treats horribly and chews out during the day is the exact same woman he is deeply in love with and sleeps with at night.
Stella undergoes a daily transformation using makeup and elegant gowns to separate her two personas, leading Callan to mistakenly believe he is dealing with twin sisters. The drama intensifies as Stella navigates his daytime cruelty and nighttime affection, eventually taking his money, his ring, and her own sanity before walking out on him.
