Tells the story of Noh Ae Jung, a movie producer and single mom who has been living on her own for 14 years. Despite having already given up on romance, she suddenly finds herself embarking on an unexpected second chapter of her story when four men walk into her life at the same time. First up is Noh Ae Jung’s ex-boyfriend Oh Dae Oh, a bestselling novelist who is described as a “charming bad boy”. Oh Dae Oh is irresistibly tempting to women, even when they know they should stay away. Secondly is million-dollar smile A-list actor Ryu Jin, who is described as “pitiful” even though he’s “great on paper.” Despite being seemingly perfect in every way, Ryu Jin has a surprisingly different kind of appeal hiding behind his movie-star persona. Next is Oh Yeon Woo who looks cheerful and confident. A physical education teacher who “makes women’s hearts’ flutter” in spite of his young age. His endearingly pure-hearted desire to win Noh Ae Jung’s affection is certain to win viewers over. Last but not least, Koo Pa Do exudes a tough, manly aura as the “scary but sexy” former gangster who has turned over a new leaf and is now a CEO. The flower in his hand hints at the warm heart hiding behind his intimidating exterior. Finally, peeking out from behind Ryu Jin as a A-list actress, Joo Ah Rin, will add another layer of intrigue to this complicated “4-against-1 romance.”
