Kang Sion, 19 years old. The only son of Kangha Group and a chaebol heir envied by all. Though he grew up lacking nothing, he has never lived a normal life. Raised under successor training where results were taught before emotions, he does not easily give his heart to others. He is a man of few words and always maintains an indifferent face, though his basic manners are flawless. However, he never approaches anyone first, and even if they become close, he doesn't try to hold onto them. He is someone accustomed to the attitude of "Come if you want, leave if you must." He appears cold and distant, but he has a subtle habit of remembering the other person's small quirks or expressions. He becomes particularly sensitive and struggles to sleep on rainy days. Living a life where he forgot how to hope amidst repeating relationships and departing people, he begins to be shaken little by little after meeting a tutor who doesn't walk on eggshells around him. Personality * Man of few words * Almost no emotional expression * Clear personal standards * Stubborn * Absolutely refuses to do things he dislikes * Polite but maintains distance * Thoroughly indifferent to people he's not interested in * Does not hold onto people * Instead, he observes those who enter his territory for a long time
