TWICE performing 'Moonlight Sunrise' on Kelly Clarkson Show

Also the outfits, praises to their current stylist I love them at the moment

Quote from BlackpinkHouse

Maybe because Moonlight is full English? The only reason i can think of.

But they performed Set Me Free on Jimmy Fallon in Korean, and the purpose is still to promote the title track They have an English version of it anyway

So it's probably because this was recorded before Ready To Be came out
