Hyo Min is the only child and she has a very close relationship with her parents. Both her parents run a cafe in Seoul and she often help out in the cafe whenever she's free. Hyo Min's father is a loving father but he is strict with her when he needs to. Her father and her loves to joke around and it makes the family atmosphere lively and happy everytime. Hyo Min's mother showers the family with love and care. Her mother is a good advisor and listening ear, thus, Hyo Min also sees her mother as her best friend and asks for her advice whenever she needs help.

Hyo Min does well in school and she even took up English as an extra lesson so as to improve her language ability. And that was how she knows how to speak English. Due to her out-going personality, she is also quite well-known in school but she still prefer to stick to her own clique. She rejected the offer to join the 'queenkas and kingkas' as they are always bullying people. Her parents taught her to be morally upright and thus, she dislikes the idea of bullying. Her parents have also taught her to be independent since young and she was more matured than any other kids at her age.

She will always try to stand up for the victims against the 'queenkas and kingkas'. But, she can't do that everytime as she can't be around every single time. Moreover, one of her closest friend in school often get bullied by them because she was plump in size. Therefore, she really wanted to get rid of the bullying problem in school. One day, she met Kristine and they became close friends.  Hyo Min shared her views on gangs with her and they both had the same view and thus, Storm was formed.

Hyo Min isn't the usual type of leader where the leader has a strict, cold or fierce image. She is more to the relaxed side but is still able to have an authority over her members. She is an out-going person and is one who keeps the conversation going. She is bold in a sense that even if she meets someone regardless whether it's an enemy, she is not afraid to engage in a conversation with them. Her out-going personality even towards her enemies surprises her enemies themselves at times. Of course, she's a careful person, being careful of what she says and does. She is also able to work her way with her words, which is to her advantage when getting information from enemies. She has a certain aura that makes people feel comfortable around her.

She is responsible and does her best in what ever she has been tasked to do. She is also firm in her decisions and will not hesitate to take the responsibility if something goes wrong. Even if she encounters any problem, she does not give up easily and she will try out other solutions to solve it. She is also an observant person, being able to notice small details (eg. someone's habit, there's something wrong with the atmosphere etc). Being quick-witted is her forte, she is able to think on the spot and react according to situations. This helps her to get out of trouble most of the time. In fights, people may not think much of her but she has her worth. She is an objective person, dealing with situations rationally and logically which can be quite useful in fights.

To her friends, Hyo Min is a loyal friend. She is someone who honour her promises and she helps them whenever in need. She is protective of them and cares about them. She is even willing to risk her life for them. In fights, she believes in "leaving no one behind". She is also a great listener to their problems and gives them advices. She is trustable that people are willing to confide in her.

However, whenever she is feeling down, she tends to keep to herself as she doesn't like others to worry about her. Everyone sees her as a happy person and they don't expect her to get angry. Of course, there's always a limit to one's tolerance. If she's really being annoyed, she can flare up. If she dislikes someone or someone is annoying her, she is not afraid to show it. Once someone gets on the bad side of her, she can make the life of that person a living hell. She also doesn't like to be told off or embarrassed as she will take it to heart and it takes some time before she forgets. She is also quite stubborn when she wants it her way.

PERSONALITY.  When you first meet JR, you will think that is a cool but also a cold guy. He only opens up to the people around him only when he feels close enough to them. He seems to have a mysterious personality, but behind this, is a guy who is actually fun and cheerful. He shows this side of him only to those who he is close with. He is a reponsible leader and he always put others before himself. He also has a powerful charisma. Lastly, he has this hidden side of him, full of aeygo which is rarely shown.

How you act with eachother.  At first, JR is always on logger-heads with Hyo Min. Usually, she tries to ignore him but sometimes, she gets mad at him and they will start quarrelling. However, they soon realise that for both of their gangs to even try and get along with each other, both the leaders have to be in good-terms first. They slowly tried to understand each other and became closer. They realise they have a lot of common topics since they are both the leaders.
