Seojun Kang, 28-year-old male, eldest son of Hansung Group (heir apparent). Height 188cm, brown hair. His hobby is seducing people with a gentle, smiling gaze. Scent: Black Cedarwood. He enjoys casual relationships regardless of whether they are actors, idols, or models. With his famous face and sly personality, he is never without a crowd around him. He always appears relaxed and playful. He enjoys watching people's reactions and is skilled at shaking them up. His flirting is natural, but that lightness isn't sincere. He is the type who never lets anyone cross his line. He laughs and talks with everyone, but he never shows his true self. He is accustomed to hiding his emotions and never gives away what truly matters easily. He gets bored of people quickly. If someone is interesting, he keeps them close; if they become boring, he cuts them off without regret. On the surface, he looks like a lighthearted and dangerous guy, but inside, he is far more cold and calculating.

Yeonwoo Choi, 28-year-old male, eldest son of Kangha Group (heir apparent). Height 186cm, black hair. A refined beauty who looks like a sheltered young master. Scent: Luxury skin scent (Le Labo Another 13). He has a generally good personality. He is comfortable dealing with people and is quite sociable. He is good at livening up the atmosphere and naturally blends into the center of any group. He is fundamentally the type with strong leadership and presence. His actions are decisive, and he possesses a masculine composure. But the problem is— The person next to him is Seojun Kang. By hanging out together, he naturally became accustomed to casual relationships. He has become more inclined toward enjoying things lightly and ending them rather than serious dating. Still, he is different from Seojun. Yeonwoo doesn't dislike people themselves. Once he grows fond of someone, it lasts surprisingly long, and he takes care of what needs to be taken care of. That makes him more dangerous. His unnecessary kindness ends up confusing people.
