Personality -

She looks like an ice queen based on the first impression with pale complexion, cold steel blue eyes that reminds a person of a white tiger on a hunt or a vampire as some had once told her and cold demeanor. The reality is that she is a cheeky, friendly, out-going, mischievous, sarcastic, curious, open-minded, loyal, independent, active, humble and tomboyish girl. It is because of her background and several incidents that had happened in the past that made her wary of people and the ice queen mask is just a front in order for her to watch people and to see whether the person is sincere in befriending her for her or because of who she is. She loves animals and her favorite animal is the cat hence the nickname kitten by her friends as she looks younger than her age and like the cat, she is a fierce and independent girl behind the "cute" looks. And like the cat too, this lil kitten's claws are sharp and mixed with a wicked sense of humor. So do not be fooled by this girl's cute cold looks because behind it all, she is like her mask's name sake a cold, cruel and ruthless person to anyone who hurts her or her loved ones. If you do try hurt or bully her or her loved ones or anyone, you'll end up with a nice er punch or being pulled into a prank that would either be funny, cruel or humiliating to you because no one would believe that the ice queen is able to pull one prank or fight with her cold, stoic, "poker" face. She is very protective of her friends and is willing to do almost anything to protect them. Most of her friends are guys hence why she is a bit of a tomboy as she loves to play sports with them especially with her friends and relatives. So it wouldn't be a surprised to see her playing basketball with one of her cousins and can shoot a wicked 3-pointer throw. But don't be mistaken that she is not feminine or boyish because she is a girl after all, just not too feminine or girly as other girls. Curiosity kills the cat as most people say but it hasn't killed this lil kitten because she is very curious and loves to learn and try out new things. As a result she is truly a jack of all trades. Some people will also say that she is a geek because she loves books and is very tech-savvy, so if you go out with her to a mall and she is suddenly MIA, do not worry, just go find her at either a book store, computer store, music store, jewelery store or shoe store and you will find her there. She is a humble girl who always kept a low profile of herself due to her background and she doesn't like to flaunt her wealth either. She likes to do voluntering works at the animal shelters and orphanages as she loves kids too. She is often involve in doing charity as well since her family is rich and is well-known for their charities. She's very hard-working and most of her spending money are not from her inheritance or trust fund as she works as a free-lance translator, model for her sister-in-law's cosmetic line of products, DJ and co-owns several nightclubs with her sister-in-law as her partner. People would say that she is a spoil brat, like her elder brother and she will tell you off with a glare that she isn't because she hasn't touched one cent of her trust fund money and inheritance. She loves to eat cold treats, cheesy food and spicy food so do not be surprised to see her at the Baskin Robbins shop on a daily basis or at 7eleven buying a large slurpee or at a pizza parlor eating a pizza with extra cheese. She doesn't really like big crowds but tolerates them enough to keep her loved ones happy so if you go out clubbing, you would either see her sitting at a table drinking with her friends or dancing with friends surrounding her nearby their table.

Siblings personality - Choi Hyunsu (older brother) - cold, strict, cunning, smart and a bit of a spoil brat as he was the only child for 11 years before his sister was born.
