On August 27 episode of KBS' music show 'Yoo Hee-yeol's Sketchbook', HYOLYN and Kim Dasom made a guest appearance.

Kim Dasom said, "All four members of SISTAR meet up very regularly. We have a group chat, and our conversation never ends there."
HYOLYN also said, "Whenever someone asks me where I am, I'm like, 'I'm with the girls.', because I really am."

HYOLYN laughed and answered, "That's what everybody says to us all the time."
Following the talk, they performed SISTAR's mega-hit songs 'SHAKE IT' and 'TOUCH MY BODY'.

For many years, SISTAR dominated major domestic music charts with their songs.
Then in 2017, the four members decided to go their own ways, which disappointed a great number of fans.
