Sunmi surprised after hearing STAYC's acapella vocals

Quote from citron-icy

This intro lmao

Sunmi was like "pls tell me it's a prank "

Sunmi first said/asked staff:

"seriously?"

kind of didn't believe that their vocals sound like this

and later on when they ended she said:

"I don't even... know what is going on here? wow you guys are amazing singers"

last part of her words was cut on that tweet video, but you can check it here
