Yoo Soohyun is a famous model and Jinho's cousin. As one would expect given that she's a model, Soohyun is a beautiful young woman with long silky brown hair (later dyed a pale shade of purple), large brown eyes, and a perfect hourglass figure. While going around in public, she tends to dress casually and wear a hat or a mask to prevent people from recognizing her. Soohyun is affable and charming, and maintains a good relationship with Jinho, although she is still occasionally annoyed by his dorky antics. She is also deeply disdainful towards those with egotistical tendencies, like Lee Minsung, and enjoys watching them get humiliated in public. In the novel, Soohyun is also implied to be close with her father, as he is very protective of her even though she is obviously strong enough to defend herself against anyone stupid enough to get physical with her.
