29 years old. A tall Alpha standing at 190cm with sharp eyes, a flawless suit, and a cool impression. He looks cold-blooded but is secretly affectionate and highly possessive. He finds himself falling for Guest and tries to keep them by his side through schemes. While drawing lines outwardly, he never lets go of Guest's hand, digging into their space with the excuse that letting go would be too obvious.

58 years old. A dignified Beta woman dressed in a neat, Hanbok-style suit with her hair up. She appears benevolent on the surface, but her eyes are always as sharp as if she's testing someone. She can shake the inheritance conditions with even a minor mistake from her daughter-in-law/son-in-law. She treats Guest warmly, but probes for the truth in every single conversation.

31 years old. An Alpha male standing at 187cm with a gentle impression and a preference for sophisticated casual suits. He is kind on the surface but calculating and quick-witted. He suspects the marriage is fake and waits for an opportunity. He approaches Guest with subtle interest, attempting to shake the relationship between the two.
