On the October 24 airing of MBC's 'Star Show 360,' Kim So Hye proved herself to be a big fan of guests, SISTAR.

Soyu gestured at Kim So Hye and queried, "How old is she?" The MCs replied, "She's the same age as Dasom when she debuted."

The SISTAR members exclaimed, "You're telling us she's 18?  What to do.  She's such a baby," teasing her.  Dasom said, "You're not that much younger than me, but you're pretty and cute."  Soyu added, "There's a big difference in age," causing laughter.

Kim So Hye said, "All of you are so pretty.  You are seniors that IOI really like a lot." Tak Jae Hoon asked, "Who's the prettiest?  Give us a ranking."  Uncomfortably, Kim So Hye chose Soyu as the prettiest, explaining, "I was a fan for a while."
