ELABORATION 

the easiest way to describe hyejin is as either a "mini hoshi" or as sixteen's moodmaker.

being an extroverted sagitarrius, hyejin has no problem with befriending people. which makes her position in the group so essential, she's practically everybody's friend. practically. she balances the group dynamic out so well. most people love her free-spirited and independent outright self. she allows her values and decisions to be based off of what she thinks is right and how her own self benefits. she is to not be swayed by anyone's mindset. she's got her own mindset. 

hyejin's goal is always to be in control of her own narrative. she takes control by being on jump of jokes and gags so that they can be her's. her goal is to always make someone laugh, and to have people laugh because of her makes her feel pride, as if she is doing something right in life. her humor and outgoing presence allows her to be a good friend. this is how she comforts people: making sure no one is left out or frowning.

whether she's aware or not, it's also a tactic to always keep people close in her life. if she can make people laugh, they will easily become her friend, and they will want to be around her. it's a form of insecurity. though her shamefulness as an idol can either make or break her, especially as a female idol in a double-standard world. though, hyejin is a tough girl and she can handle it, no matter what the pledis officials say. she likes making a fool of herself, so that no one else can. she's going to do what she wants.

though the girl has such wit (that can get her in trouble sometimes) when necessary. sometimes she lacks it. meaning a lot of the time. she can have her head in the clouds alot, allowing her dorky "dumb blonde" moments, in which turns into multiple fan compilation videos. the girl is free-spirited, but also head strong. the way she won't falter for anyone is really real. it's not that she is technically hot headed, she actually is a quite relaxed, laidback person on most issues. but when she feels attacked or accused, it's the manner in which she can get angry. it's actually quite scary and aggressive, always a few levels higher than anybody else's anger in the situation. and she can come strong, especially since she does not get angry about little things. zero to one hundred real quick if you are truly asking for it.

like most humans, hyejin can lack awareness, especially on faults caused by trauma she does not know she has. while she is a good friend, always willing to make you feel better and put your mood above hers, she's also not that reliable. she tends to fly like a bird to her own drum, often forgetting whats on the ground. this gets annoying for issues like chores or planwith friends. it's something about commitments that she can't seem to shake.therefore a lot of times she is viewed as lazy, despite being a hard worker in what she sets her mind to.

BACKGROUND  

her whole life, hyejin has been greatly influenced by her father. mostly her father. that's what happens when you have a mother walk out on you. born in the chilly fall busan, with a 3-minute "younger" brother to call "twin", hyejin was born to a young, unmarried couple. being in their mid-20's, the couple didn't have much but hodong's rising dance career. but that wasn't enough for his girlfriend; she did not know if she could handle the job of being a mother in such an unstable state in her life. so one day she left. and the twins were only 9 months old. 

so her father, hodong did what ever he could to raise his kids, with the help of his family, while his dancing/choregraphing career took off. he tried his best to provide for them, in the long run becoming a big choreographer and owner of a pretty famous hip hop dance school in busan. of course, having their father only to look up to, the twins became students at the school, easily being prodigies and becoming top of their classes. 

knowing of the dance school, pledis scouts would often go to the biannual showcases the school would throw. the january of 2014, the school had their first show case of the year, where scouts were attending. after the show, hyejin was handed a business card with the pledis logo on it, which she greatly accepted. being the supportive father he is, hodong allowed hyejin to audition with the promise that she gets accepted and works hard to be a trainee. needless to say, the family packed their things and moved to seoul mainly for hyejin's trainee career, and secondly as an opportunity to create a branch of the dance school in the capital. hyejin's been training since late january 2014.
