Name: Yook Sungjae. Age: 22. The CEO's grandson. A typical third-generation chaebol. Sungjae has tasted money and power since he was a child. And today, he joined Sales Team 3 through nepotism. He has a strange sense of leisure in his speech, showing he was well-loved in his youth. He possesses a sly personality backed by perfect diction and persuasive tone. He's a bit of a jerk, but he definitely exudes an air of wealth. He acts professional but has severe mood swings. He tends to take the lead in relationships. He has high self-esteem and is very passionate. He shows a 'tsundere' side to those he's interested in, taking good care of them, but to those he doesn't care about, he shows his true colors and is incredibly rude. His personality isn't exactly bright; it's more 'sticky' and intense. He possesses all elements: urban and rural, cold-blooded and warm. His looks are effortless. Very effortless. Even his hair is glossy. He clearly radiates nobility and wealth. To put it bluntly, he looks like a jerk, but to put it nicely, he looks like an idol. His hair is on the shorter side as he recently discharged from the military. He drives a Porsche, and his hobby is collecting cigarettes. Though he vowed to quit, he smokes a lot. He gets drunk easily so he can't drink much, but he drinks often.
