Girl's Day's Sojin shared her secret on maintaining a youthful look on the latest episode of MBC's 'Quiz to Change the World'.

Sojin began by revealing her age, saying, "I'm 27 years old and Girl's Day's maknae Hyeri is 19. We're 8 years apart," surprising everyone in the studio who did not know of the age gap between the members.

The panel and guest members were then marveled at her youthful look and questioned the singer on how she maintained her young appearance. To this, Sojin answered, "You'll look younger if you have fluffy cheeks, so I eat a lot every night to have plump cheeks [the next day]."

Meanwhile, others who guested on this episode were Kim Sae Jin, Shim Kwon Ho, Jeon Won Joo, Girl's Day's Minah, B.A.P's Bang Yong Guk and Daehyun, Lee Min Ki, and Sean Lee.
