On the June 17 episode of “Welcome Show,” the members of SISTER make an appearance in the midst of comeback preparations.

gugudan’s Kim Sejeong is excited to meet her sunbaes and gives them a big bow, saying, “I really respect you.”

Kim Sejeong cautiously says, “I prepared just a little bit of dance, but the problem is that I’m really bad. I’m really bad.”

But SISTAR cheers her along and obliges when Kim Jong Kook suggests that they join Kim Sejeong in her dance.

“It’s an honor,” Kim Sejeong says as they come beside her.

Kim Sejeong and SISTAR together perform snippets of “Push Push,” “Touch My Body,” and “Alone.”
