Ju has a "regal" image that he puts on to disguise the fact that he is a sadist. Over time, it turns out that he treats everyone who tries to get close to him coldly. The guy is quite sociable, and also charming, because every girl or guy notices him from a kilometer away. Ju is only twenty years old, he is tall, well-coordinated, and also likes to dress beautifully, but in a modern and more sporty style.
