She has been honing her vocals since she was little and after becoming part of SM, the company does well in promoting her skill, which makes the netizens acknowledge her and look forward to her debut.

⟪ Position ⟫ Main Rapper

After SM successfully debuted Mark and Taeyong, who are both managed to be acknowledged as talented rappers, this time, it's the girls' time to shine. She'll probably be SM's first girlgroup rapper who really knows how to rap and is a pro at it. Her stage presence is no joke, she burns the stage when she raps and she's definitely the girl crush material. Even so, she's not too pleased with the group's main dancer.

⟪ Name ⟫ Lynn 
⟪ DOB ⟫ June 26 1997, 21
⟪ Position ⟫ Main Dancer

Having been familiar for years in the dance world, this girl's skill is no joke. The word champion follows her name everywhere she goes. When she dances, she is the brightest and no one can take her eyes off of her because there's just something in the way she moves that will captivates you and you'd find it hard to look away. Though, she has this tendency to outshine other members when she's dancing. It's because she dances so well but she often forgets to match her pace with the group, who's not as better as her in dancing. She's also not the best teacher in helping her members-often getting pissed and impatient at members who's lacking in dancing skills. At stage, it's painfully visible that she outshine the others. Bad news is, since she's in a group, they're supposed to have a synched pace, synched move and be in one harmony. You can't be the only one shining when you're in a group.

⟪ Position ⟫ Lead Vocalist, Visual

Hyojae or Daisy, has been famous for her pretty looks ever since SM introduced her through SMRookies. Blessed with her alluring, innocent beauty, strong aura and good proportions, she managed to seal herself a good amount of fans and land herself in pictorials and photoshoots even before debut. She is SM's jewel, the newest addition to SM's flower garden. However, one thing she lacks is attitude. She's reserved, she's not kind, she has forked-tongue and she has temper which easily hurt others around her. She also doesn't seem to try and make new friends when she thinks the other person's not worth her time. Honestly, she's not a daisy but a thorny rose.

⟪ Name ⟫ Vivian 
⟪ Age Range ⟫ March 16th 2000
⟪ Position ⟫ Lead Vocalist

With her lovely face and even lovelier voice, when SM first introduced her through SMRookies, it's hard not to fall in love with her. She has wide vocal range, her voice is melodious and clear and it's one of her many charms. Her shy, quiet personality gives her a captivating vibe that draws you in, making you curious in getting to know her. Is often babied by the group, must be protected at all cost. But because she's babied, this girl is very, very sensitive. She gets offended really easily and a bit uncomfortable with some of the members who don't seem to have a brain-to-mouth filter. Out of the rest, she's the most distant in the group, often preferring to hang out with her true friends or herself rather than joining the members.

⟪ Name ⟫ Aria 
⟪ DOB ⟫ October 7 1997, 20
⟪ Position ⟫ Lead Dancer

She got the wits and killer moves, this girl is quite an all-rounder of the group. Her confidence is her forte and it is the strongest when she dances. She is the variety queen, the ultimate stan-attractor of the group. She's just so full of charm and always says the right thing at the right moment and never fakes her personality that people can't help but to fall in love with her. She's also famous for her down-to-earth and kind personality and alongside the Main Rapper and the Lead Rapper, she's the beagle-line of the group. Is often compared with the 'true' visual of the group (Saeran) because she's equally pretty and she has what Saeran hasn't : variety skills and outstanding social skills; which bless her with LOTS of fans. However, this causes friction between the two, since she dislikes Saeran's 'more superior-than-thou' attitude and labeled her as a stuck-up antisocial. God knows there's a time bomb between the two. Their constant bickering is a countdown to a big fight.

There's no denying the reason she's chosen as the leader because she's 100% capable of it. She's the strong mommy.
