When you first meet Naeun, you might mistake her to be a quiet or shy girl. She's not really either. In fact, mostly, Naeun is known for being serene. She prefers peace over drama and excitement, but that's not to say she doesn't like those things. In fact, she seems to thrive in those environments, because they can keep her attention for longer than a few moments. She likes quiet places and intellectual conversations with people. If you can managed to keep up with her bouncing topics of conversation, she won't hesitate to talk your ear off, either. For the most part, Naeun is that girl that's considered oblivious in the back of the room and everyone assumes had no idea what's going on. However, that's not the case. For the most part, even if she looks like she's off in lala land, Naeun hears almost everything, and her brain tends to file it away for use later.

However, there are a few times you don't want to interrupt Naeun's thoughts. She's very possessive about her writing journal, and unless she gives you the okay to read something, she won't hesitate to give you an earful (mostly with a few English curse words thrown in there) about how it's disrespectful to look through other's things without their consent. She has the bad habit of, if she feels threatened, getting snarky to the point of boardering on rude. It's a natural defense for her, since she was bullied when she first came to Korea for being from America. She's not a victim, and she'll never allow herself to become one. Most people who cross her leave with a splitting headache from a knowledge overload and high pitched screaming. Naeun isn't against showing her emotions, though getting her to pay attention long enough to show them is not an easy feat.

Naeun was born to James and Kimberly Choi. As their second born child, and second girl, the Choi's were happy. They named their infant child Naome, along with giving her a traditional Korean name of Naeun, as well. Natalie was three when Naeun was born, and due to the birth, began acting out, as her attention was given to baby Naeun. Her parents said that was the point when Naeun and Natalie's sibling rivalry began. Even though growing up Naeun never really understood what she had done to Natalie, and she tried to remain close, Natalie always seemed to push her away. When Naeun was almost three, the Choi's had another child. This time, it was a boy. They named him Nathan, and the family was finally complete. The university professor and his librarian wife began honing what they often called the 'greatest thinkers of the coming times.

From a very young age, the Choi's introduced learning and knowledge, instilling a reward system for learning, and Naeun found she enjoyed learning the things that her parents taught her. Once she reached the age of four, she began trying to learn on her own. She learned to read and write early, and by the time she was eight, she was reading on the level of most middle school children. It was at this point that the true rivalry between Natalie and Naeun started. Natalie felt like Naeun was trying to outdo her, and Naeun wanted to be the best. The harder they fought, the farther they grew apart. It got so bad at one point when Naeun was twelve, that instead of sharing the bunk bed with her sister, she had Nathan switch, since they didn't fight nearly as bad. Natalie was always overly emotional in Naeun's opinion, and Naeun was always anti-social in Natalie's. As time went by, they only pushed farther apart. Nathan was very clearly the favorite sibling of Naeun's, as they did quite a bit together. He never looked down on her aspirations to sing, and still learn.

Naeun auditioned for SM entertainment when she was 15, but was not accepted. However, JYP did take notice in the young girl from America, and just after her sixteenth birthday, sent her an invitation to join their company as trainee. The Choi's were overjoyed for their middle child, who's dreams were coming true, although they were worried about her learning and schooling. Upon making sure that she would have proper housing, food, and schooling, the Choi's put their youngest daughter on a one way flight to Korea, and sent her to start her dream with the words that eventually became her motto- "Love like you'll die tomorrow, and learn like you'll live forever." Naeun will never admit to it, but she was scared, anxious, and apprehensive of going to Korea, but she wasn't giving up her dream either. She would become an idol, and she wouldn't give up her ways to do it.

Naeun's Korean was decent, but they immediately signed her up for classes when she arrived to begin training. The focus of her training was to well-round her, as she had potential in all areas, and not in the learning of the language. Naeun was often the chosen for "stress-bullying" as she called it, due to her lack of the language, and the fact that she came from America. For two years she ruthlessly trained, but when her parents realized that Naeun knew very little more about the language she was speaking, they decided to see who else was interested in her talents. Both SM and YG took interest, but Naeun had always wanted to be in SM, and her parents chose thusly. Once Naeun was transferred into SM through a swap of trainees that JYP wanted, as well, she began rigorous language classes. They already knew she had the talent, now they needed her to speak the language fluently. It took another year and half before Naeun felt comfortable speaking Korean only. At this point, SM began honing her skill to decide if she was going to be someone they debuted or not.

It was during the last two and a half years of her training that things started happening. Naeun's focus started drifting, and she had a hard time paying attention to her training. Six months went by before SM sent her to neurologist, looking for a reason why one of their leading vocal trainees suddenly started acting so strange. Their diagnosis, however, was not something SM was prepared for. Naeun had developed Epilepsy. Seizures of the brain. The doctors put her on medications that were supposed to help, but they barely kept her more attentive. However, she was able to hold entire conversations, and her abilities only seemed to multiply. SM finally decided that they were going to debut Naeun, but they would keep her sickness quiet. No one but her bandmates and manager needed to know. Not even her family.
