Soohyun is always very energetic and cheerful. Likes to enjoy herself and is happy all the time, since the early day until the late night. It's really unusual to she see her sad or crying. If crying it maybe from happiness. Soohyun is a very lively girl. She's very active and thinks that her life must be lived at the fullest and to her the fullest is all the happy and funny things it happened or will happen in her life, so Soohyun usually just thinks about those moments that makes her laugh. People around her tend always to have a smile placed on their faces because of Soohyun's jokes and pranks. A very optimistic girl, expects all the best of the best in every situation. Soohyun tend to be very positive about everything, when everyone is thinking about the worst she manage to find the good thing about it and usually makes everyone laugh because her ideas are always weird. Soohyun is also an easy-going girl and doesn't really care much about things and one of them are what people think about her, she just ignores them or just go along with them laughing at anything they say, but there are times when she's really laughing because she finds herself funny.

Soohyun may be a little bit lazy about somethings, it's rare to see her working, but if she's really determinated to do something she makes up her mind and will accomplish that no matter how hard it is. She likes to watch people that's why she is good at reading people specially the ones that she's closest to. She knows them really well. Knows what they like to do, things they like, etc. That makes her say what they think beforehand and don't let them talk which annoys everyone. Soohyun is also a girl that gets distracted easily. When she's doing something or going somewhere if she gets distracted by something she forgets what she was doing and ends up not doing it. When this happens she always has the felling that she forgot about something and ends up remembering when she's in the middle of a conversation. The person usually is shocked because Soohyun shouts an 'AH!' from nowhere. No one can ask her to do something because of her distration problem but most of the time is because she doesn't want to do it, since she's lazy, and pretend that she didn't hear it or that she forgot as an excuse. Soohyun has this habit of lying since she was young. There's no way she can keep a promise or see if she's saying the truth. It's better not believe in everything she says or else it will make you very disappointed although lying sometimes helps her get out of scary situations or get out from troubles.

There were a few times when her friends also told her that she was weird because when she is immersed with her thoughts then she remembers something and starts laughing by herself even if she's alone with a million people around or when she started yelling at her phone because it's not working or a tree if she hurt herself on it. Soohyun is also full of herself, specially if someone praises her, she feels like she's the best in the world and starts showing off all her good and bad things that she thinks that are good. but it doesn't mean that she will hurt someone. Another flaw Soohyun has is being an irresponsible person. She forgets easily about assignments and sometimes doesn't care about the consequences of her actions. Being a very lively girl, might sound that she's very childish, but not, she can also be serious when it's needed. If there's something wrong and no one can be poisoned by her happy side, instead of trying to find the best way about it, she tries her best to help and solve the matter. If she's has her showing off mode on, soohyun usually turns it off. Soohyun's also very competitive, specially in sports, since she thinks that she's good at it, or in things that she's good at. Of course being a competetive girl she doesn't like to lose.

Soohyun was born in South Korea just like her two older brothers. Both of her parents are average people that works in a restaurant. Because they have family in Los Angeles, Soohyun's parents they decided that when Soohyun was in 2nd year of elementary school, since she would know how to speak korean by that time. They went to America and made a living there. Her father had already been in Los Angeles a few times to visit his older sister and had the honeymoon there so they were quite familiar with the place. Of course, Soohyun and her brothers made a big fuss about it because they would leave their friends but they couldn't do anything since they were too young to do argue with them. Like what they were expecting, at the beginning it was though for all of them, they relied a lot on Soohyun's father older sister which was glad to help them but after learning the language everything became more easier. Soohyun's parents opened a korean restaurant in Los Angeles with the help of Soohyun's aunt and Soohyun and her brothers went to school there. The three of them were a little bit afraid but they found great friends there that helped them with the language and other things. They also found one or two korean students that made them less stressed for living in a foreign country.

Soohyun started liking music when she went to America. Her cousins, who were already in high school when she started living in Los Angeles, always heard pop music that were popular at that time. She became addicted to Taylor Swift and Katy Perry singing skills when she was 10 and started taking vocal lessons since then, of course after asking her parents. She also started to write her own songs and she would show her work to her family like in Christmas or dedicate a song to one of her relatives. A year after she also started taking guitar lessons. She still conected herself with South Korea which made her know about K-Pop and when she learned almost everything about idols, trainees, the big companies and how the auditions worked she decided to take an audition to Overlord Entertainment since they were going to make an audition in Los Angeles. Her parents that always supported her daughter went to the auditions with her and when she got accepted, she moved back to Korea with her older brother because he wanted to attend college in his hometown, her parents would stay there with her young older brother. After moving back, she started to be a trainee and started going to Seoul Of Performing Arts where she met other idols that had already debut and be friends with them.

Gongchan may look stiff when we first meet him because of his tall build, chic appearence and pretty face that intimidated his hyungs when they met him but he's actually a very dorky, playful and cheerful boy full of aegyo. He may be the maknae of B1A4 but he can take care of his hyungs, since he has a younger brother, sometimes he may look like the hyungs while s are the younger ones. We can always count on him whenever we need him, he's a very reliable friend and is always willing to help his friends and close ones. Gongchan is also a happy-go-luck guy. He enjoys playing around even when he's alone he plays by himself for not to get bored. Like Soohyun, he loves to compete and getting into the games, just having fun is good for him. Sometimes he's deep in his thoughts which makes him quiet and make him look like he's a bit of a cold person but he's just pondering about something, sometimes things that are even not important like what he should eat for dinner. When he's thoughts are interrupted by someone he usually goes back to himself. Gongchan has a smile that is contagious, he makes everyone around him smile because of his weird but funny pranks which he does to his hyungs and other friends.

Soohyun met Gongchan through her trainee friends. He was a little bit shy back then but Soohyun tried hard to let his playful side come out. They used to hang out together and play around or eat something when they were trainees but after Gongchan's debut they couldn't do it so often although they still kept contact with each other. Soohyun always teases Gongchan because he takes more time than her to choose clothes to wear for some event and to pay back Gongchan is always touching and messing Soohyun's hair which she hates it. In their trainee days, everytime Gongchan would want to prank one of their friends he would ask Soohyun for help because she has good ideas for it. Everyone that hangs out with these two never get bored, they are always loud and joking around even when they send messages to each other, it's funny to read them. When they are together they often jokingly insult each other but they are great friends and always cheering and supporting each other. When Gongchan debut they promised each other that they would meet in a music show and drink green tea although they rethink about the green tea, they don't know why they choose that.
