When I was first new to the fandom, Leo was my bias. He was so shy and so adorable with animals and . Then he would get really excited about singing and has a powerful stage persona ( like a lion) but then he would be a fluffy kitten when he was on variety shows. Yeah, I was a goner.
As I got more in to the fandom though, Hakyeon started growing on me. He is the one that I find most relatable. I like his energy. I can't really articulate why N started becoming my bias. It just happened.
So, who is my bias? Well, I have two: Leo and N. They are each my bias for different reasons, but I love them both and can't choose between them.
