After the first episode was aired, Kyung Soo Jin -- whose name doesn’t sound too familiar to us -- was praised by many, not for good acting but for her youthful look. Kyung Soo Jin appears in the drama as a high school student but it turned out she isn’t that much younger than Son Ye Jin. Son Ye Jin is 31 and Kyung Soo Jin is 26. To netizens’ compliments that she looks young, Kyung replied: "Son Ye Jin is the truly youthful-looking actor."
