The Red Velvet members were asked who they'd like to collaborate with for a special stage, and Joy expressed, "I want to sing with Black Pink's Rose. She sings really well. I'm a fan of Rose's voice." She continued, "If we can collaborate together, I'd like to be on stage with her. We suggest a lot of songs to each other, so I think we could pick a song quickly together."
Yeri added, "I'd like to work with TWICE's Nayeon unni. We're close friends, and she's cute and sings and dances well. I think it'd be fun."
