Lee Hwi Jae's wife Moon Jung Won was taken aback to hear her mother in law's way to raise a child on KBS 2 TV entertainment program "Happy Sunday: Superman Returns."

On KBS 2 TV entertainment program "Happy Sunday: Superman Returns," which aired on January 19, 2014, Lee Hwi Jae's wife Moon Jung Won visited her mother in law's house for her mother in law's birthday. On this day's episode, Moon Jung Won was bewildered to see her children on the rides at her mother in law's house, but strove to smile. Later on, when her mother in law told Moon Jung Won, "I made them eat some of the potatoes," Moon Jung Won was bewildered again. Later in an interview, Moon Jung Won said, "I was so surprised to hear that the children have eaten potatoes that had butter, sugar, and whipped cream. I will definitely bring this up to my mother in law when she is in a good mood."
