Kei and Mijoo from Lovelyz made an appearance in the recent episode of tvN's "Amazing Saturday - Do Re Mi Market."

Nucksal then commented, "I've met someone who is even tougher than Hyeri." When the song played on, Mijoo lip-synced passionately.

During the episode, Mijoo said she was much more the same with Girl's Day's Hyeri out of all the cast of the variety show.

"I think we share a positive, bright personality. We both like being friendly. And she's really pretty," the Lovelyz's vocalist said.

"If Hyeri flips her hair, Mijoo also flips her hair," MC Boom said.

Hyeri then quipped, "If you keep flipping it like that, you'll get a cramp."

Later on in the episode, the two ladies were asked to do a competition to be the "one-shot" subject, and Kei, who was sandwiched between them, reacted, "This is very competitive"
