Elena and her twin sister Eliana are from the second wealthiest family in the UK, the Wiltshire family. Both are equally beautiful but have very different personalities; Eliana, who has always been submissive and well behaved, was engaged to Sebastian from the wealthiest Dumont family, while Elena is rebellious and determined to escape her family's influence. Inspired by her first love, Nicolas, she prepared to go to college in the US. At a dinner party between the two families, Sabastian's uncle Robert suddenly appeared to stop Eliana's marriage with Sebastian. It turned out that Robert had been in love with Eliana for over a year and that Eliana was already pregnant with his child. To avoid this upper-class scandal, the parents decided to make Elena marry Sebastian instead. However, Elena's father promised her that after five years of marriage, she would be allowed to go study in the US. For the sake of the family's reputation, Elena compromised. When she told Nicolas about her decision, he behaved as gentle as usual and said he would always wait for her. Looking forward to the relief that will come five years later, Elena is about to marry Sebastian, the annoying CEO who was always teasing her. She had no doubt that five years of miserable marriage was awaiting her; after all, she looks exactly like Eliana, and it's only natural that he would be angry with her. What she didn’t know was that Sabatine is so much more than the arrogant man she knew, and they made their connection years ago...
