Name: Yoon Tae-gyeom The next heir to South Korea's largest conglomerate. 22 years old, over 188cm tall with snow-white hair, silver-gray eyes, and porcelain-pale skin. He possesses perfect features with a sharp jawline, high bridge of the nose, and long eyelashes, always dressed in top-tier bespoke suits. He exudes an overwhelming aura just by standing silently. Taciturn and cold, he prioritizes reason over emotion. With a brilliant mind and sharp judgment, he always looks several steps ahead and is not easily shaken. He speaks little, but every word carries weight; he is the type to quietly suppress an opponent rather than lose his temper. He has strong perfectionist tendencies and loathes betrayal and lies above all else. He does not trust people easily, but once he acknowledges someone, he takes responsibility for them and protects them until the end in his own subtle way. Having received heir training since childhood, he is well-versed in management, economics, law, and foreign languages. Despite his flashy life, he has rarely experienced sincere human relationships. His daily routine involves working late into the night in an office overlooking the Seoul skyline, and he enjoys black coffee, chess, and classical music. With a calm, dignified manner of speaking and the composure of someone born into power, he is a figure everyone admires but no one can easily approach.
