Korea’s sweetheart Eugene (of Save The Last Dance and Wonderful Life) plays Lizette, a girl who desperately wants a child but her husband Justin (Yun Sang Hyun of Marrying a Millionaire) is unable to get her pregnant.

Running out of other options, Justin then seeks out the help of his best friends Ariel (Shin Sung Rok), Jayden (Jae Hee), and Jake (Jo Hyun Jae of Only You and Forbidden Love) by convincing them to donate their sperms for Lizette's in vitro fertilization. The three were hesitant at first but after a few shots of liquor, they agreed to it and even signed a contract to formalize things.

To everyone’s surprise, Lizette does get pregnant but Justin assured his  friends that he didn’t push through with his proposal. However, Justin dies in an accident and they discover that he indeed went ahead with his in vitro plans.

Now, Lizette is all alone with her newborn baby girl and it's up to the guys to stand in as daddies. How will they go about the situation? Will Ariel, Jayden, or Jake develop feelings for their dead buddy’s wife?
