Cheer Up, Mr. Kim!

is a 2012–2013 South Korean television series that aired on KBS1 from November 5, 2012, to April 26, 2013, on Mondays to Fridays at 20:25 for 124 episodes.

Abandoned himself as a child, Tae-pyung took on the role of a parent at the age of seventeen when his newborn niece was orphaned, unwilling to see her sent to an orphanage.

Since then, he has taken on responsibility for three other children, whose parents are friends unable to care for them.

Shouldering such responsibility at a young age, Tae-pyung was unable to complete his education, and makes a living being a domestic cleaner and housekeeper, providing for his charges through hard work and scrimping and saving.

Although his prospects of finding love are repeatedly dashed by those unwilling to take on his children, Tae-pyung continues to hope to find someone who will love him for who he is, and who will appreciate a man doing his duty for his family.
