ISTJ-A / Scorpio / Slytherin / True Neutral
Personality.

Hardworking and zealous : Miyeon gives her all in performing as it has been her dream to perform on stage for a long time. She makes sure to practise until she can remember all the lyrics and hit all the right notes or memorise every move of a choreography and execute it perfectly before she goes for evaluations, often staying up long after the other members to practise alone.

Loyal and protective : It's not easy for Miyeon to make friends due to her resting face and cold nature, so she greatly cherishes those she who have proven her she can trust them and sticks by their side no matter what. If someone tries to badmouth someone she's close to, she will defend them with her life and attack them mercilessly.

Responsible and caring : Miyeon makes sure to look out for her members and keep them out of trouble. She keeps the promises she makes, and even if her heart is no longer set on something, she commits to it. She won't say "I love you" out loud, but she'll show concern for the other members in small ways like asking them if they've brushed their teeth or eaten their meals, wishing them good luck before evaluations or other important things and scolding them when they are reckless.

Cold-hearted : Though Miyeon cares for her members, she has no qualms being cruel to them either, especially when she feels they are slacking too much or not putting enough effort into training. Other than her members and people she is close to, she generally doesn't care about the well being of others. Her goal is to make it as an idol, and if she has to be the bad guy to achieve this goal, she doesn't mind doing so.

Strict and rigid : To Miyeon, failure is defeat, and therefore, she puts pressure not only on herself but also her members to be disciplined, put all their effort into training and get everything right, because to her, that is exactly how to avoid failure. She makes sure she follows her schedules and the rules set for her exactly, and often reminds her fellow trainees to do the same, even scolding the members she cares enough about for not doing so.

Irritable : Going along with Miyeon being strict and unable to stand a lack of discipline or half-assed effort during training, she will fly into a rage when she feels her members are slacking too much and / or not giving their best, or even if you simply did or said the wrong thing at the wrong time. And once you've annoyed Miyeon, she'll yell at you till the cows come home, until she has been appeased.

Reserved : Miyeon doesn't believe in socialising simply for the sake of socialising, or up to someone she does not like. She'll only let you get close to her if she decides she likes you. Even so, she will take a long time to open up to you. She usually keeps to herself, only speaking up if she has a strong opinion, if she needs something or someone speaks to her first.

Honest : Miyeon believes that in order to correct someone so they can improve, they need to be told exactly what they are doing wrong. Therefore, she doesn't sugarcoat her criticism and doesn't care how insensitive she is when telling people off. However, if she has praises to give, you can be sure they are from the bottom of her heart.

Stubborn and petty : When Miyeon’s mind is set on something, she’ll do everything she can to get it. Don’t try to tell her what she should do or what’s good for her, she won’t listen. Be careful not to upset Miyeon, because she's not one to forgive easily and holds grudges.

Cocky : Miyeon knows she is pretty, and that her many years of tranining have made her very talented. Because of this, she tends to look down on the members who are not as talented and / or did not train for long.

Competitive : Since young and during her training days at Pledis, Miyeon had been often compared unfavourably to Siyeon. Because of this, Miyeon felt that she had to outdo Siyeon to be noticed. Even though they're now in different companies, Miyeon still feels that she has to do better than anyone else around her if she wants to be on top. If Miyeon feels other people are "stealing" attention from her, This Means War. She'll fight anyone who she believes to be stealing her thunder relentlessly.

Background.

Miyeon was born in 2000, with one twin sister, Siyeon. Growing up, while Siyeon was intelligent and a fast learner, Miyeon was not so smart and slow to pick things up. During her childhood, Miyeon had often unintentionally been compared negatively to Siyeon by her parents and relatives, and while Siyeon earned many praises from them, praise towards Miyeon was few and far between. Siyeon was smart, pretty and talented in singing and playing instruments, and as hard as Miyeon tried, she was never able to match up.

In 2008, Siyeon wanted to take part in Pledis Superstar. Not wanting to lose out, Miyeon decided to participate with her sister. Both sisters eventually became Pledis trainees, but while Siyeon shot many CFs and dramas predebut, it seemed that Miyeon was always cast aside for another girl who was prettier or more talented. She just wanted everyone to believe she could be as good as her sister. She tried not to mind that Pledis didn't debut her in After School or Hello Venus, despite the fact she was far too young to debut then. But when Siyeon was chosen to participate in Produce 101 without her, it just hurt Miyeon more. Why couldn't Pledis see that she too was trying her best?

Finally, in 2017, Miyeon decided to leave Pledis. She knew Siyeon was the princess of Pledis and if she could have dethroned her sister, she would have done so years ago instead of being stuck in the basement all these years. Miyeon auditioned for many companies but was constantly told "sorry" or "better luck next time", until she went for an audition for a company called Unite Media and was accepted. After several months of training at Unite Media, Miyeon was chosen to participate on their reality show, International Idol, and later became one of the eleven members that formed the final team.

Relationships.

Sister / Park Siyeon / 18 / Idol / Cheerful, sweet, hardworking, zealous, outgoing / Miyeon had often been compared negatively to Siyeon when they were younger, and Siyeon had been more successful than Miyeon ever since they were in Pledis. This made Miyeon resent Siyeon, and want to do anything she could to one-up her twin. However, they say absence makes the heart grow fonder, and indeed, sometimes, Miyeon does find herself missing her sister. Deep down, Miyeon does love Siyeon, but she'll never explicitly admit it.

Groupmate / Arlo Yoon / 22 / Idol / ENFP / Miyeon doesn't approach Arlo much outside of practise / trainings. She finds the boy too loud and crazy for her.

Groupmate / Hirose Yumeko / 22 / Idol / INFP / Yumeko is shy and Miyeon is reserved, so they seldom approach each other outside of training. It doesn't look like that's likely to change, because Miyeon's bad temper and fierceness intimidate Yumeko too much.

Groupmate / Luna Tuan / 25 / Idol / ESFJ / Miyeon looks up to Luna, because somehow the older girl has the leadership skills and motherly vibe that Miyeon seems to lack. Knowing Miyeon is a difficult child, Luna is very patient and caring towards the younger girl.

Groupmate / Lee Haero / 24 / Idol / loyal, confident, ambitious, brave, straightforward / Haero is beautiful and confident, and she loves to flaunt herself, so naturally, she gets a lot of attention from fans. Which makes Miyeon dislike the older girl, because she doesn't like attention seekers and people who steal the spotlight from her. Plus Haero is completely straightforward when she talks, and never fails to give Miyeon a piece of her mind when the younger girl is being a spoilt brat.

Groupmate / Liang Wenxin / 28 / Idol / she doesn't know but she just thinks Wenxin is a / Like Miyeon, Wenxin is beautiful and mysterious, so the older girl gets a lot of attention from fans, to Miyeon's frustration. Miyeon never fails to hurl insults at Wenxin, sometimes in the older girl's native Mandarin. Truthfully, Wenxin has no time to bother competing with Miyeon, but it doesn't mean she'll take the younger girl's attitude lying down. When Miyeon throws an insult Wenxin's way, you can expect the both of them to get in a huge shouting match.

Groupmate / Tanaka Mina / 19 / Idol / caring, kind, brave, outspoken, quarrelsome, talkative / Mina loves the members of U/idol dearly, and that includes Miyeon. That doesn't stop them from getting into arguments though, as both are headstrong and bad-tempered. Truthfully, Mina wishes she didn't have to yell at the younger girl so much, but she can't help but get emotional when Miyeon is being difficult.

Groupmate / Ariga Shinobu / 25 / Idol / INFJ / Shinobu loves and cares for each and every member of U/Idol, including this difficult child. The two don't talk much, but Shinobu believes he can make the ice princess melt.

Trainee Life.
Everytime Miyeon saw girls being chosen to be part of a group, her heart sank a little. Sure, she was only 9 when After School debuted and 12 when Hello Venus debuted, but she had put in hard work training. It didn't help that Siyeon managed to rack up experience in CFs and dramas, making Miyeon wonder what was it about her sister that she lacked. In 2015, when Siyeon was chosen as one of the representatives for Produce 101 and when Pristin debuted in 2017 and Miyeon did not make it to the lineup, she almost broke. It hurt to see her sister doing so well and earning praises from everyone, while it seemed nobody loved her.

Realising that Pledis would never let her be as good as her sister, Miyeon decided to leave the company in 2017, and later was accepted to Unite Media. However, being in a different company from Miyeon didn't make her lose her competitive edge, and while at Unite Media, Miyeon constantly fought to reach the top, so she could be in the spotlight as fast as possible. And she got her wish when she was chosen to participate in International Idol, and better yet, she was one of the eleven finalists.

Comments/questions. Hope you don't mind her personality being similar to Wenxin / Citrus' Chaehee.

Suggestions. I would like to see a scene where Miyeon gets a craving for fries out of the blue, and Siyeon (or another member) brings her a packet of fries despite not knowing she was craving for them.
