One is Sana from Twice because she's the reason I got into K-Pop and we're also very similar and I just love her so much, she's so talented and has the best personality. I'm honestly not confident in her being my ult bias anymore but she still has a very special place in my heart.
The other, my true ult, is Yeojin from Loona. She has one of the most unique voices I've ever heard, she's a triple threat (technically quadruple if you count her rapping skills), and she's the funniest person alive. The more crackhead stories I hear about this girl the more I love her.
