Free-spirited Alpha Do-gyeom has finally decided to put her promiscuous past behind her and settle down. As a 39-year-old woman, however, her options for marriage partners have dwindled. Luckily she has her beleaguered Omega secretary, Seung-ah, to do most of the work of finding a suitable match for her. It shouldn't be a problem, even if Seung-ah and Do-gyeom have harbored secret feelings for each other for years. In fact, arranging Do-gyeom's marriage may just be the catalyst for the two of them to finally admit their attraction...unless another Alpha gets in the way!
