Personality 
—   When you first take a look at Seoyun, you would think she doesn't want to be here. But, that's not true, she's an introspective girl, always in deep thought, especially with the extroverts in the groups. With this, she is able to think logically when making decisions, and it takes a long time when officially making decisions. She is also conscientious, always striving to do what's right, and is very hurtful is she isn't. She is also attentive to mostly every detail and people, especially with the younger members. Seoyun is generous, always willing to help whether its for charity or just helping the staff. She is not afraid to lend a helping hand. Growing up, Seoyun has been a brilliant girl. She is very book-smart, and uses difficult words that most people don't know, she's almost like a walking dictionary. As continued in the negative side, she likes other people to know how smart she is. She always has a book in her hand, and would read it whenver she finds time to. Seoyun is versatile, being able to adapt into new situations and settings very comfortable and easily. She can understand situations and environments easily. Seoyun is always ready and excited to learn new things.

— Seoyun being bad-tempered is obviously a problem, as she doesn't know how to take criticism as that well, but she's also working how to not be too sensitive of how other people view her. She is the most like this when it's the morning and night, she gets very cranky and easily offended when tired. Even so, Seoyun is kind of a hypocrite when she is being judgmental of other people. She sometimes judges other people's personalities and opinions. From an outsider's perspective, people would often think that Seoyun does not like the people she's with. Though, that's not really true, as she is just judging people based on their actions. She is clearly shown when she is judging something, so it's easy for people when identifying when she is. Whenever someone does something wrong, she's kind of selfish and culpable, thinking that it's her fault. With this, she feels bad that she disappointing people. She is insecure of herself at times, and always worried whether or not her or the people she cares about fails. Coming back to Seoyun being a brilliant person, she tends to be a smartass; a know-it-all. She loves to have people being aware of how smart she is, and it gets annoying after a while. As she is not aware of this, hopefully she'll become aware and tone down of her pushing her knowledge to other people. 

Background Kwon Seoyun was born on November 21st, 1995 in Vancouver, Canada to her parents Kwon Dongkyu and Kim Yikyung. She has one brother; Kwon Yunho. Yunho is 2 minutes older than Seoyun, making them twins. Seoyun's family had a wealthy business in Canada that went bankrupt. Soon enough, Seoyun and her family moved back to Daegu, South Korea when she was 6 years old.
Seoyun's parents eventually got a divorce when she was in the first grade, where her and her brother lived with their dad, while her mother still having joint custody. Growing up, her father has always raised his kids in a middle class healthy lifestyle. He would make them work out every morning before school. He also raised them to be more educated, resulting in the kids to be more grown up and fit than the other kids.
Seoyun was in taekwondo and modern dance ever since she was in the second grade. There at modern dance, she had grown to love dance and music. But unfortunately, her parents were not really into the whole entertainment industry, they wanted to kids to grow up well educated and cultured.
Seoyun was first introduced of the idea of becoming an idol by Yunho's best friend, Choi Seungcheol who was becoming a Pledis trainee in 2010. He saw potential in Seoyun of becoming an idol. So, Seoyun auditioned for Pledis Entertainment along with Seungcheol. He was accepted while Seoyun was rejected. Although she was sad, she kept on auditioned until she finally got accepted into Pledis in mid 2012.
Her and her parents kept going back and fourth as to her becoming a trainee, but her parents eventually gave in and let her moved in with her aunt and uncle in Seoul when she was accepted as a trainee. So, Seoyun trained as  Pledis trainee up until late 2015, where she eventually figured out that Pledis had no plans for her so she terminated her contract and went to train for Moon Entertainment in early 2016 in hopes to debut faster.

family

— Father : Kwon Dongkyu / 53 / Doctor / Attentive, Strict / 6-10 / fc: Lee Youngha
Despite Seoyun growing up strictly by her father, she is still close to him. They haven't talked much since Seoyun moved out of thehouse back in Daegu, but once in a while, he would check-up on her. He and Seoyun is closer than Seoyun's relationship with her mother.

— Mother : Kim Yikyung / 55 / Social Worker / Strict, Introspective / 5-10 / fc: Choi Myunggil
Seoyun and her mother do not interact as well as those mother-daughter relationships. Her mother kind of disowned Seoyun when Seoyun had wanted to become an idol, and wouldn't talk to her for months, but now, they are getting better at being there for each other.

— Twin Brother : Kwon Yunho / 22 / Law School Student / Attentive, Caring / 10-10 / fc: Yook Sungjae
Seoyun's brother is really overprotective over Seoyun. Ever since Seoyun was born, Yunho had been wanting to protect her form everything bad in the world, it's a brotherly instinct. By this, the two siblings are really close and can depend on each other.

friends

— Close Friend : Brooke Hopkins / 21 / College Student / Assertive, Witty / 9-10 / fc: Jessie Paege
Brooke is Seoyun's friend from the Canada. The two were childhood neighbors. The two met when Seoyun lived in Canada, and hit it off right from the start. Though, they had grown apart when Seoyun moved to Korea. During the summers, they would often visit each other and catch up.
— Friend : Lim Nayoung / 22 / Idol / Reserved, Thoughtful / 8-10
The two had orginially met when Seoyun was a trainee at Pledis, where they had become good friends. Because of their close personalities, they had gotten along with each other than other trainees quickly. They haven't spend enough time together now that they're more busy, but would find time to hang out.
– Groupmates / Rose /  8-10
When the idea of Rose had rung into Seoyun's ears, she wasn't on board from the start. She had always thought she would debut in a small-members girl group, not a 12 member group. But overtime, Seoyun had given into the idea. She is more closer to her unit.

other

—  Pet Cat : Bijou / 1 / Axious, Friendly / 11-10

Bijou means jewel in French. Seoyun shares the 1-year old cat with her brother who is currently living in Seoul. Bijou has separation anxiety, so she clings onto Seoyun as much as possible when Seoyun visits her. Bijou doesn't really likes to meet new people, but overtime she would come to love everyone.

— Little Brother Figure : Kim Samuel Arrendo / 15 / Idol / Easygoing, Polite / 7-10

Because of Samuel's young age when he was training at Pledis, Seoyun felt the need to protect him. Seoyun had always wanted a younger sibling, so she considers him as one. Once in a while she would check up on him, seeing if he's doing okay.

Trainee years 4 Years (3 at Pledis, 1 at Moon)

Trainee life Seoyun was first a Pledis trainee before she was a Moon trainee. As all trainees do, Seoyun trained really hard. She would train throughout the nights and day, sometimes only having small meals whenever she's really hungry. Although she had some spotlight with being on live shows and concerts, she felt underappreciated between the other trainees. She left after 3 years of training at Pledis because she felt she wasn't going anywhere. Although, she kind of regretted leaving since she would've had a chance to be apart of Pledis Girlz that would've debut under Pristin.
She then went to audition for Moon Entertainment a few months after leaving Pledis and got in. Seoyun was thinking whether or not to still training. Fortunately, she decided to keep running to her dream and not give up.
When the idea of Rose came up and Seoyun would again be one of the contenders for the members, Seoyun didn't know if she would like to be a member of the group. She was very worried, as it is a big-member group and she didn't know if Rose would debut or disband. Seoyun ultimately decided to take the risk and she joined the group.
