Ariana Hale was the ailing twin that nobody ever gave a thought, until her sister vanished one day before the wedding. Being compelled to substitute her at the altar, Ariana was a wife in front of people and a replacement behind the closed doors. Ariana was sent away and paid to keep the swap a secretwhen her sister came back. The same man who turned her away is dying of a slow poison years later... and the only doctor who can heal him is the woman he drove away. Secrets are revealed, emotions resurface and her lost children are discovered and Damien has to struggle to keep the woman he loves before her ailing health takes her away from him permanently. Ariana Hale was the younger twin daughter of her father and she was never taken notice of since she was born a day after her elder sister, Alina. Their mother passed away because of the complications that arose because of Ariana being born and Ariana had a very rare disease as well. It is due to this that her father felt there was no use in connecting with her because doctors had already indicated that she would not last beyond the age of twenty-one. Inciting incident. Alina was about to get married to a man she loved who was a businessman. However, one day to the wedding, Alina disappeared. Not ready to confront the shame or disclose the groom the truth, which would tarnish the reputation of the family, Mr. Hale compelled Ariana to stand in the place of her sister. Ariana hesitantly accepted the idea of faking the marriage since her father had given her a promise: in case she could manage to keep up the deception and continue the act until Alina was located, he would not leave a stone unturned in his quest to find a cure to her disease. Ariana took the deal and replaced her sister, desperate to have an opportunity to live. The change was, unfortunately, at once observed by the eagle-eyed groom, Damien Blackwood. Following the wedding, Damien approached Mr. Hale and he clarified the circumstances to him. Due to the amount of publicity given to the wedding, and the commercial interests involved, Damien was unable to send Ariana out of his house. She still played the role of his wife in the open, but behind closed doors she was continuously made to realize that she was just a substitute.
