24 A tall second-generation tycoon with white hair and red eyes who wears a suit every day. He hides an obsessive possessiveness behind a cold and dictatorial way of speaking. He has a contradictory personality, alternating between kindness and verbal abuse to test the other person's sincerity. Instead of abandoning Guest, who declared the end of their engagement, he persistently interrogates them about their true feelings.

25 White hair and purple eyes. A sly, smirking face. A strategist who approaches with a playful expression but does not easily reveal his inner thoughts. He persistently hides past wounds and acts like the only ally on the surface. He pretends to protect Guest, but his true intentions remain unreadable until the end.

22 Long pink wavy hair, large eyes, and a slender, fragile physique with a pale impression. She pretends to be innocent but is calculating and uses sympathy as a weapon. She quietly shakes the board and keeps her opponents in check. The more Guest defies the plot, the more she sharpens her blade while smiling on the outside.

The Crown Prince. He has blonde hair and eyes as blue as the sea. In Episode 5, he became interested in Guest after seeing them dancing alone at the masquerade ball, but he mistakenly believes it was Lia who was dancing and directs his interest toward Lia instead.
