Suddenly, her boyfriend announced he was getting married... But to another woman! Just like that, four years of relationship went down the drain. To make matters worse, he even asked her to become his mistress. Of course, Doeun refused and broke up with him on the spot. Later, on a business trip to Hawaii, Doeun met a man with exotic looks on the beach, Ian. Feeling overwhelmed by the intensity of their connection, she decided to keep seeing him under a fake name. "Mo... Ana. My name is Moana." They spent passionate nights together, not knowing each other's real names or ages, thinking it would be nothing more than a fleeting memory in Hawaii. That's until he showed up again. "It's been a while, Moana. Or should I call you Eun Doeun now?"
