Oh! Minha Dama (2010)

they are both about an older women trying to get there lives together but find love on the way.

In both dramas, there's a "older woman-younger man" relationship.

Choi Si Won as main role again. Although he is arguably completely different in this drama (as he is even speaking a different language), he is just as amazing in this! I recommendand it completetly!

In both dramas the femal lead gets paid to take care of the male lead's child who was abandoned by their mother.

both shows have artists who are thought to be incapable of taking the role in an entertainment show but proving everyone wrong by the help of that certain older lady...

Here as well the female lead goes to the househouse to take care of his child, leading to them falling in love

The plots of these dramas a are very different, the into thing that was similar was vine from both. In both dramas, you have an older married woman (or recently divorced as in OML) working with a younger man and finding commonalities as they get to know each other. Both are slow burn noona romances.

both are noona romances, both female leads are +35 year olds with a daughter and their ex husband cheated on them. and they both also work as a "housekeeper" for the male lead...

It have the same plot. An actor with a daughter no one knows he had and the complications that hiding it, brings.

A capable but unpopular showbiz manager, Kazuko, struggles to groom a younger, new male actor, Ryo, whom she had scouted, into a star. An unmotivated Ryo slowly becomes conscious of the pleasures of acting. Bonds of camaraderie grow, and before long, love gradually blossoms between them.

A spunky 35-year-old housewife, Yoon Gae Hwa, takes on the job of manager to prickly top star Sung Min Woo in order to earn enough money to regain custody of her child from her ex-husband. Romantic hijinks and hilarity ensues when they find themselves in an awkward living situation as Min Woo pays Gae Hwa to take care of his daughter, Ye Eun.

Both male leads have a child from previous relationship. Both female leads work as a maid/nanny.

Both rom coms are about a younger man falling for an older woman. In Baby Faced Beauty, the story is more about her professional growth-- whereas Oh My Lady is more about the male lead's personal growth.

Both shows are noona love stories. OML is about a super star who learns to be a better man as he leans to love and take care of his child. BT&SC is about a neglected and rebellious high schooler becoming a better man thanks to his love for his teacher.
