Synopsis 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 and brings his mother along in secret, arranging for her to be picked up at the airport by his girlfriend, Yoon Sae Wa, an ambitious TV announcer who harbours a secret disdain for Anna’s disability. Dong Hae meets Bong Yi, a poor assistant chef, when Sae Wa prioritizes her job and sends her to meet Anna instead. After Sae Wa later betrays him, Dong Hae begins to search for his father, creating a new family and finding new romance along the way.
