I keep hearing Red Velvet when I listen to “RUDE!” by Hearts2Hearts

It’s probably Carmen or Ye-on they sound the most like Joy and Seulgi

Maybe because I’m used to their voices RUDE! Sounds like them to me but I had the same thing with Butterflies where I swore I could hear both Seulgi and Joy

Edit: also Ian really sounds like Irene at least to me!
