Although he may not seem like it, Danny has a very complex personality. He is most obviously, usually very optimistic and cheerful, rarely seen with a dark expression on his face. He's very expressive and open, and tends to be quite blunt as well. He has his times where he can be a little sassy, a little snarky,but uses his sense of humor to cheer others up around him and tends to have a very playful banter with friends. He's naturally pretty intelligent without really trying, coming from a family of geniuses, and picks up things fairly quickly.
Danny seems like just another happy-go-lucky friend magnet. However, he hides more than you might think. Although appearing very confident in manner, deep down he really isn't and always has a shred of doubt, questioning everything he does. Being someone who is normally driven by impulse and spur-of-the-moments, he tends to regret them later on.
Danny always cares deeply for his loved ones and they're constantly on his mind, to the point where his heart for others overshadows his own self preservation. His greatest fear is hurting the people he cares about, and sometimes in his efforts to avoid hurting them he'll make a lot of sacrifices - and usually they're not worth it. He's someone who, although he may not seem like it, always learns from his mistakes and always remembers his past mistakes, so he can make sure they never happen again.
Danny tends to hide a lot of anxiety and stress under the surface, and worries too much about certain things. Some of these fears are even irrational, but he can't really help it. It just happens.
Seo Jungeun and Seo Junghyun were both born on Jeju Island to a witch mother and a Muggle father. Their mother, Lee Eunseo, hailed from a wealthy pureblood family who were at first against the marriage, but her parents decided to support her wholeheartedly as long as she promised to expose her children to wizarding culture. The father, Seo Seokho, came from a successful family of businessmen. However, since his older brother inherited the company, he was able to marry Eunseo, whom he had fallen in love with. He was aware of her magical blood but came to accept it.
When they were only four, the Seo’s decided to move to England to immerse their children in the vibrant wizarding community there, and in hopes they would attend the prestigious Hogwarts. The Seo couple were close with another couple, Yoo Kyungtae and Somin. The Yoo’s were in a financially tight spot, and the Seo’s offered to help by bringing one of their sons, Changhoon, with them to England. The Yoo’s agreed, and Changhoon’s twin brother stayed with the parents while the Seo’s brought Changhoon along to England to start a new life.
The three each adopted an English name-Jungeun became Crystal, Junghyun became Daniel, or Danny, and Changhoon was known as Caiden. The three lived together in the new Seo family mansion, and essentially grew up together.
From the start, Crystal and Danny were complete opposites. They shared some similarities, but often did not see it. They looked nothing alike, and often Crystal was confused for older while Danny for younger. While Danny was outright and mischievous, Crystal was discreet and modest. Studious pupil Crystal was favored by their parents, and while Danny also excelled he never showed much fervor in his studies. These differences and more caused the twins to not be particularly close, though they never had a bad relationship. They just sort of left each other alone. Danny wreaked havoc with Caiden and Crystal read books - that was it.
At the age of eleven, all three received their letters for Hogwarts and began their first year there. They are now in their sixth year.

When around amortentia, he smells rich coffee, the salty scent of the sea, a musty wood smell, and oddly enough, fresh-baked cookies and what he thinks is lemonade. He can associate the coffee with his sister and his parents, the sea with his birthplace of Jeju Island, the wood smell with the piano he always used to play, but he can't figure out why the last two are there. Maybe Crystal liked cookies?
His Myer-Briggs' personality type is ESFP-T - Extroverted, Sensing, Feeling, Perceiving, and Turbulent.
He's actually a very talented singer, and can occasionally be caught humming to songs he likes, but he's never, ever, going to sing out loud for anyone.
Danny's also exceptional at playing piano, but like with his voice, he isn't going to share this fact anytime soon.
