'Superman Returns' Choo Sa Rang became so quiet in front of her boyfriend Yuto. On the KBS 2 TV entertainment program "Happy Sunday - Superman Returns," which aired on March 9, 2014, Choo Sa Rang's dad Choo Sung Hoon babysat Choo Sa Rang and her boyfriend Yuto. On this day's episode Choo Sung Hoon took the two kids to a restaurant. He helped Yuto eat, but Yuto took the spoon out of Choo Sung Hoon's hands and started eating his food by himself. Yuto ate a lot of food at the restaurant, gulping down a steak sandwich in addition to grilled chicken and a soup. Choo Sa Rang, on the other hand, ate so quietly and ladylike, unlike her titular title of goddess of food, and made the audiences and fans laugh.
