Roman, the billionaire magnate of a hotel empire, has long harbored a secret crush on Siena, his own PR assistant. To get closer to her, he deliberately had her write a "wife-winning guide," then systematically used the tactics within it to woo her. From clearing out a luxury store for private shopping and showing off his physique by the pool, to orchestrating alone time during a blizzard, various clever schemes unfolded one after another. When Julian, a wealthy venture capitalist, started pursuing Siena, Roman's jealousy flared, and he promptly acquired Julian's company. Siena was deeply moved upon realizing all the elaborate ploys were for her, and the two confirmed their mutual feelings. Roman grandly proposed with a private island and an exorbitantly priced diamond ring. A magnificent wedding brought their journey to a perfect conclusion, as they vowed to spend the rest of their lives fulfilling the final strategy of the "wife-winning guide."
