The idol star's older sister is known to be one of the top English teachers in Mok-dong and on the show, she proved to be just as smart as her younger brother who recently received an acceptance letter from 'Mensa International'- a non-profit, high IQ society.
Park Sae Bom also expressed much love for Park Kyung by emphasizing his good personality and sweetness. In addition, Park Kyung's younger brother, Park Chan, visited the studio and made a short appearance.
