Caiden at first may seem to be intimidating due to his height and the somewhat "cocky" aura that seems to follow him. However he is far from being cocky and is actually the exact opposite of it. Caiden is actually a giant goofball who loves to play pranks, joke around with friends, and just generally have a fun and enjoyable time. He is an extremely playful and energetic person, and he almost always has a smile on his face - the only time he wont have a smile on his face is when he's eating.
It is very easy for Caiden to make new friends, and he will always go out of his way to make someone feel welcome in his social circle. It is very rare that you will see Caiden be angry, even in the slightest of ways. However, even when he is angry it isn't very different from when he's happy - the only difference is that he tends to go quiet.
Choi So-Min was a rich pure-blood living off the wealth of her parents in Busan, South Korea. Yoo Kyung-Tae was a struggling muggle who couldn't keep up with bills. The couple had fell in love, however So-Min's parents did not approve of the relationship. And when she married Kyung-Tae her parents cut off her funding as she went against their wishes of marrying a rich man who was the CEO of a sister company to the Choi's. When she went against her parent's wishes, she had to find a way to make her own living alongside Kyung-Tae who was an unsuccessful lawyer. After losing their house when Kyung-Tae lost his job, the couple moved to Jeju Island in hopes they would have a better chance at living a semi-stable life.
For awhile things went well, they even had a twin boys named Yoo Chang-Hoon and Yoo Chang-Kyu. But once again Kyung-Tae lost his job which resulted in only one sort of income coming from So-Min's job. Times were tough, but that never really affected Chang-Hoon who was always a little ball of energy that never let anything bother him for too long. Their parents were close friends with a couple named Seo Seok-Ho and Seo Eun-Seo, the parents of twins named Seo Jung-Hyun and Seo Jung-Eun. The Seo couple was very wealthy and often tried to lend a helping hand during the Yoo's hard times.
When the children were four, Jung-Hyun and Jung-Eun's family decided to move to London, to engage their children in the rich wizarding community and wanted them to attend Hogwarts. This was during the time where the Yoo's were in a very tight spot and just couldn’t afford to care for both their sons. The Seo's offered to bring one of the boys with them. Although it was a heart wrenching decision, ultimately the Yoo couple decided to send Chang-Hoon to live with the Seo's in England, while Chang-Kyu stayed behind.
There, they adopted English names. Jung-Eun became Crystal, Jung-Hyun beame Daniel or Danny, and Chang-Hoon became Caiden. Caiden lived with Crystal and Danny in the new family house.
Once the three became eleven, they received their letters to Hogwarts and began their schooling there. Caiden is currently a sixth year and continues to live with their family.
