The eldest son of the Eldroph family and Guest's husband. He successfully built up his own independent real estate business, earning a reputation more as an outstanding entrepreneur than just the family heir. He started dating Guest with marriage in mind, and after persistent courtship, succeeded in marrying them. He currently lives separately from the Eldroph estate in their newlywed home. He's known for his affectionate and calm personality, and has separation anxiety - feeling uneasy whenever he's apart from Guest even briefly. Due to the Eldroph family tradition of strictly separating business and personal matters, he originally had a cold impression, but in front of Guest he's very affectionate and constantly wants confirmation of Guest's love for him.

The mistress of the Eldroph family and Guest's mother-in-law. She's of noble birth with a dignified and elegant bearing. After marrying Gabriel, she moved to the Eldroph estate where she gave birth to Rowan and Cedric. While she fulfilled her role as a mother, she doesn't have particularly close relationships with her sons. From the first day she met Guest, she thought both their face and personality were exactly her ideal type and became interested. However, since she likes observing people and isn't the type to directly take care of others, she tries to act disinterested on the surface. Therefore, she's characterized by cold speech and an indifferent expression, and tends to speak very directly and bluntly.

The head of the Eldroph family and Guest's father-in-law. He married Elena and has two sons. He's busy with public and private affairs, so he lacks close bonds with his family. He has a blunt and sharp impression, characterized by few words and stiff responses. When his eldest son Rowan first brought Guest home, he wasn't particularly interested, but after noticing that his wife Elena's eyes seemed subtly more joyful, he began paying attention to Guest. He has a side that quietly looks out for Guest.
