The 17-year-old performer Kim So Hye confessed during the October 24 episode of South Korean variety program "Star Show 360", how much of a Sistar fan she actually is. Shyly, the young singer emphasized that for her, Soyu is the prettiest among four members.

As reported by allkpop.com, Sistar were invited to the MBC variety show where Kim currently panels with hosts Leeteuk and Tak Jae Hoon.

Kim originally started from Mnet's reality girl group program  "Produce 101"  and later on became a member of the performing group produced by the same show-Ideal of Idol (I.O.I.).

When Soyu asked the hosts how old Kim is, they replied, "She's the same age as Dasom when she debuted."

Dasom, one of the vocalists of Sistar, started at age 18. However, Kim is still 17 to which the group replied, "What to do?  She's such a baby!"

"You're not that much younger than me, but you're pretty and cute," admits Dasom. But Soyu teased, "There's a big difference in age," making everyone burst to laughter.

And being polite as always, Kim responded that all Sistar members-Soyu, Hyorin, Dasom, and Bora, are pretty.

But the hosts didn't settle for that. Since the group is considerably one of the "sunbaes" or senior compared to I.O.I, Tak insisted, "Who's the prettiest?  Give us a ranking."  Shyly, Kim admitted she finds Soyu the prettiest, adding she's really a fan.

Aside from Kim So Hye, I.O.I. has 10 other members selected from a pool of 101 trainees from various entertainment companies-Lim Na-young, Kim Chung-ha, Kim Se-jeong, Jung Chae-yeon, Zhou Jieqiong, Yu Yeon-jung, Choi Yoo-jung, Kang Mi-na, Kim Do-yeon and Jeon So-mi.

The group debuted on May 4, 2016 with their first mini-album, Chrysalis.

Meanwhile, Kim So Hye represented Red Line Entertainment while she was still on 101 but has already transferred to S&P Entertainment. It was her own company, created last June to focus on her career as a performer. Kim, who has no background in acting at all, is also trying her best to improve for the benefit of their group.
