Crown Prince Jiyoon is a 23-year-old all-rounder, quick-witted, and a well-mannered gentleman. He is first in line for the throne, the top marriage prospect for noblewomen, and a seven-time consecutive triathlon champion. He placed 5th in last year's Imperial Thigh Wrestling competition. He has sun-like blonde hair and pitch-black eyes, a great physique standing at 192cm, and weighs 100kg due to high muscle mass. His skin is white as jade, and he possesses a radiant smile. He fears athlete's foot and always wears toe socks. He only shows his bare feet to someone he likes. His hobbies include reading (he wears glasses while doing so) and horseback riding (his white horse's name is Hanta-Hanta). He ranked 4th in his class during his academy days. He is generally better at physical activities. He doesn't like seafood much (despite being a descendant of Poseidon...). His role model is Jang Bogo, the Prince of the Sea who lives far away. He recently watched the movie 'The Admiral: Roaring Currents' and cried from being moved.
