Normally this girl is already loud and crazy, but with Chocolates she'll turn hyper and can go louder and crazier. A real fact though, "if you want a spirit lift after having a long bad day, give her a Chocolate bar (Hershey is recommended), and get ready for a good laugh of the day."  Even though she is spontaneous, but she can be very serious and mean if the situation require her to be.

As much fun as she is to be around with, she is also very straightforward and bossy. She order people around a lot, just because of her laziness. Sometimes she can be a little too blunt that she'll hurt someone's feeling in a snap. At the same time she is sensitive, one harsh word can bring tears to her eyes. Some people might not consider her as a shy person, but her close friends know very well that she is actually very shy. Well only around her crush. She tend to be very quiet, and you can barely here her talk. This is like a whole different side of Joori that nobody expect she'll have.

Background – She was born in Albany, New York. Her mom is a business secretary, while her dad is a psychologist. She have a big brother, he is older than her by 8 years. Their family isn;t rich neither is poor, middle-class it is. When she was 5 years old her parents put her along with her 13 years old brother in a Taekwondo class for self-defense, they're now black belt. In middle school and 2 years in High School, she was the School's Girls Basketball Captain. 

Her brother, Jay, was a K-pop idol, leader of 2PM. But in 2010 he left due to his Myspace controversy. When he came back to New York he started uploading cover of songs on Youtube, Joori had featured in some of them. In the same year 2010, when Joori was 15 years old, she got a call from a scout from YG asking her to become trainee, because they saw her video with her brother where she rap, sing and dance. They thought she got talent, just need improve on her singing.

Personality: Kai is a caring and nice person toward everyone. He is warm-hearted and cute, love dogs. He can be annoying if he wants to. He is a good friend, have a passion for dancing. A little dork, do stupid stuff, and hates to be laugh at. He like to order people around, like a boss.

He is very awkward when it come to expressing feelings. He is sometimes like a bipolar, can be all smileys and hella pissed off the next minute. He doesn't like explanation at all, he want proves. If you don't have proof, don't bother explaining anything to him, because he won't listen. Can be mean and agressive if he gets annoy.

How do you act each other?: She try be friend him, but he just seem too arrogant. He at time get irriated because of her none stop talking, he did made her cried a few times. Sometimes he treat her awkwardly when they're alone. He just don't talk to her much, which make it look like he doesn't like her, she was hurt thinking of that.

She did try her best to talk to him, but he just ignore her and be mean. As a bipolar like he is, he sometimes started get all smiley around her and annoy her, that kind of scare her. But most of the time Kai just treat Joori like a stranger, worse than a stranger, he would be cold and mean. He irritates her too.
