The Mafia's Wife Replacement

Stellina did not expect that her life would change drastically when Diego, an Underboss of the Pacnozzi mafia clan, asked her to be his wife. Of course the request was not based on love. Because Diego only wanted to use Stellina to replace his wife, Vellina, who died in a car accident. Stellina, who look similiar to Vellina, could not refuse Diego's request when the life of the father she loved so much was at stake. When Stellina finally joined the Pacnozzi family to replace Vellina, she seemed to bring a warmth that had never filled the mansion until now. Arianna, the daughter of Diego and Vellina really loves her current mother because Stellina treats Arianna with great affection, unlike Vellina who always snaps and scolds her all the time. But somehow, Vellina's cousin Matteo finds out about Stellina's identity and blackmails her. Stellina could not tell Diego for fear that Diego would stop her father's health treatment if Diego found out that someone else knew Stellina's true identity. How will Stellina deal with this situation and save herself in the mafia's lair? Will Diego let the woman who has slowly stolen his heart fight alone?
