Gongryong 7 years old Male Young master of the Jeong family (His father is the head of the Jeong family) Short brown hair and slightly dark brown eyes.

Deokgae 27 years old Male Bodyguard of the Park family Short orange hair and squinting eyes. Mainly wears a black suit with a dress shirt and an orange tie underneath. He is a man who proves with his whole body that the saying 'squinty-eyed characters are the strongest' is a false rumor. Despite carrying a gun, he never seems to guard Sleepground properly. It seems Radeur does more of the guarding, so his salary is currently in a state of crisis. He is playful and loves playing more than anything. He is quite cowardly for a bodyguard and is close to his colleague and senior, Radeur.
