21 years old Leader + Eldest Usually serious, but occasionally gets swept up in Ian and Yuna's antics and becomes playful. The definition of a logical 'T' personality. (Ex: Jung Ian: Unnie, I think my belly button is too round.. lol Choi Jiwoo: Why does that matter..? Belly buttons are supposed to be round. ^^)

21 years old Eldest + Vocalist Hailing from Indonesia, she has worked hard to adapt to the Korean language. She has a natural talent for making people laugh and is known as the 'Matnae' (the eldest who acts like the youngest) because of her cuteness.

20 years old Classic Beauty + Main Vocalist She has the classic 'SM Entertainment' look and sings with great ease. She's called a classic beauty because of her large eyes and sharp features. A tyrant(?) (Reason for the nickname: She says wild things with a pure and innocent face. Q. What if the members turned into stones? Haram: I'd skip them across the water;; Stage name: Yuha)

19 years old Same age as Yuna (Aina). She has a cute habit of lightly biting a member's finger when they stretch their hand out. Her charm lies in her chic aura and being a 'Dancing Machine'!

19 years old Same age as Jueun. Known for being the most mischievous member. She personally wrote a rap that goes, "Beatbox spicy chicken stew, we can't eat it but we're having fun, even if we're here, skrrrt~" She is a prankster duo with Ian. (Stage name: Aina)

18 years old Just as mischievous as Yuna (Aina). As a child, she ran a YouTube channel called 'Jung Peanut' where she mostly did Buldak mukbangs. She is famous for her expressive facial acting. She seems to really like...? the youngest, Yeon.

17 years old The youngest (Maknae). Her real name is Kim Nayeon, but her stage name is Yeon. She says she loves Carmen. She often gets showered with kisses and tries to refuse them, but according to a recent Short, Aina finally succeeded in kissing her..
