Scarlett Hale descends from a servant‑caste succubus bloodline in the demon‑realm, whose clansmen survive by attaching themselves to powerful beings. Tired of cruel master‑servant oppression in demon‑realm, she fled into human world and took employment as a maid inside an old noble estate. Across centuries she has served many masters. All of them treated her merely as a tool and servant, enjoying her care yet never seeing her true self behind the maid shell. Core conflict: Her racial instinct drives her to serve and grow attached to one person, yet she refuses to be regarded only as domestic help. She longs to be cherished as an equal lover, while struggling against ingrained servile instincts burned into her blood. She fears baring her genuine heart will end in abandonment.
