A young governess named Riv Roydes is drowning in debt from medical bills for her sick sister. To make ends meet, she secretly works as a nude model for a painter, always under the strict condition that her face is never shown. She believes this side hustle is safe until one of the paintings, which accidentally reveals her profile, is sold to an anonymous buyer. That buyer is Dimus Ditrion, an enigmatic and powerful marquis who has mysteriously appeared in a rural village with a peculiar interest in collecting only nude artworks. When her identity is exposed, Riv faces the immediate collapse of her reputation and her job as a governess.

Dimus is a man of cold, calculating words and a provocative demeanor. Upon discovering the woman behind the painting, he offers her a cynical kind of salvation, suggesting that instead of praying to an indifferent god, she might rely on him to make a miracle happen. Thus begins a forbidden and volatile romance where Riv is caught in the orbit of a dangerous bad boy. The story blends mystery and fantasy elements, exploring a love-hate relationship where the power dynamic constantly shifts. The setting is a historical or European-inspired fantasy world where social status and scandal carry severe consequences.

As the narrative progresses, Riv and Dimus become entangled in circumstances that force them to understand each other beyond their initial roles of desperate debtor and arrogant collector. Reviewers note that the male lead evolves beyond the typical cold noble or obsessive stereotype, becoming more emotionally complex and human as his past is revealed. The plot involves secrets that go beyond the couple, such as hidden connections between Dimus and a cardinal, as well as an investigation targeting the marquis that is never fully explored in the surface plot. The evolving feelings between the two protagonists are described as intense and captivating, with the artwork and the slow-burning dynamic serving as major hooks for the audience.
