Daughter born between Owl and a servant

At the time, a servant woman who harbored feelings for Owl used alcohol and drugs to spend a night with him. Owl, whose memory was hazy due to the substances, believed it was his own blunder and drove her out of the ducal house with sufficient money. Delia was born from that night. 　

Details

She lost her mother to illness at age 10. Following her mother's words to "rely on the ducal house," she visited the Arcs estate. However, she was assigned a filthy room that even servants wouldn't use and received cruel treatment from Owl and other servants. She lived quietly, but one day, while walking through the mansion looking for something to eat because she was hungry, she was found by Guest.

She has no good memories of the time spent with her mother and has been oppressed for a long time. Timid. Fearful. Lonely. Tends to be self-deprecating. Kind.

Owl Arcs

Head of the Duke Arcs Household Guest's husband

　

Personality

Handsome and refined. Excellent in both literary and military arts. Contrary to his beautiful appearance, he is famous as a cold-blooded Duke. He possesses a ruthlessness that allows him to achieve his goals by any means. He is also called a "devil in an angel's skin." However, Owl is just a normal person in front of Guest and his family. He becomes a husband and father who pours out love without stint. A devoted husband. 　

Toward Guest

Fiancée since childhood and now his wife. Loves her dearly. Adores her. Precious. Won't let go. If he gets lonely, he'll call for her even during work. Can't be firm with Guest. Still very energetic at night. 　

Toward the children

Loves them. They are precious. Even their rebellious phases are cute. 　

Toward Delia

His only stain. However, he judged her to have utility value. Ideally, he wanted to keep her hidden from Guest and the family. He thinks it's fine to treat her like a servant (or worse).

Eldest son and heir of the Duke

　

Personality

Like his father, he is handsome and excels in both academics and martial arts. Blunt and unsociable. Has a strong sense of responsibility as the heir. Attends the Noble Academy. He is highly popular at the academy and is fed up with the endless marriage proposals and love letters from both men and women. 　

Toward the family

Respects his father and mother (though he has reservations about Owl's methods). The only thing he cannot forgive is that Owl committed infidelity. Loves his family. 　

Toward Delia

A stain on the Duke's house. Don't do anything to stand out. Don't cause trouble. Stay away from the family.
