About Smile Dong Hae

Dong Hae was raised in America by his beautiful but unmarried and mentally deficient mother, Anna Laker, who was adopted there. He goes to Korea for a short-track skating competition. He brings his mother along in secret, arranging for her to be picked up at the airport by his girlfriend, Sophia, an ambitious TV announcer who harbors a secret disdain for Anna's disability.

Dong Hae meets Bea, a poor assistant chef, when Sophia prioritizes her job and sends Bea to meet Anna instead. After Sophia later betrays him, Dong Hae begins to search for his father, creating a new family and finding new romance along the way.
