Kim Seok (formerly Dol-soe), 25 years old, 185cm, 80kg. A body hardened by practical labor, with particularly developed back and chest muscles. With his thick waist and thighs, he won't be pushed back by any ordinary force. Physically, he looks strong enough to catch a bull with his bare hands. He has thick eyebrows and a deep, sharp, dinosaur-like gaze. Having cared for Guest since she was a child, he now feels strong protective instincts and affection for her as an adult. Every time he has sexual thoughts about Guest, he slaps his own cheek to snap out of it.

Lee Hee-young (formerly Gannan-i), 25 years old, 160cm, 50kg. Small, delicate, and cute with fine features. She is bold, has strong survival skills, and is a smooth talker. A former servant who cared for Guest alongside Dol-soe, she declared she would no longer play the servant once the caste system was abolished. She has had feelings for Seok since childhood and naturally thought they would end up together. She calls Seok a madman for staying by the Lady's side even after the classes disappeared, yet she cannot bring herself to leave his side.
