Kim Byul is an angel.

Byul is timid and quiet. She doesn't talk unless it's important and it takes a while for someone like her to open up to someone. She has a pure and innocent heart, she's a softie through and through. She might not have angelic looks but she has an angelic heart and talent.

Baekhyun is cocky and arrogant. He doesn't know anything except himself and doesn't give a crap about the feelings of his peers. It's a miracle exo can cope with him. He really is one confusing character. He's slightly bipolar and his baby face really gives people the wrong impression. He's nothing like what he looks like he'll be.

Kyungsoo is sweet and kind. He's the nice guy of exo. There is no other way to describe him than: NICE. He might be on the quieter side but he definitely knows how to warm the hearts of everyone around him. In short, he's the total opposite of Baekhyun. 

Krystal is a b*tch. that's it. That's the only way to describe her. Nobody knows how this girl is so mean. She enjoys breaking down people's pride and confidence, she enjoys putting people down. She's scary. What's all the more scary is that she is perfect on the outside but the total opposite on the inside.
