Claire Adeline was forced to swallow a bitter pill when she caught her fiancé, Arthur Blackwood, having an affair with her stepsister, Natalie. To save her own self-respect and her family’s honor, Claire agreed to a substitute marriage with the mysterious "disowned grandson", Julian Blackwood. Rumored to be a rough man, asexual and working odd jobs, Julian was in fact a formidable figure hiding his true identity as the ruler of Empire Group. After the wedding, Claire moved into a luxurious apartment in Namba and began to realize Julian was her secret protector. Though bound by a "no physical contact" contract, romantic tension began to grow between them. Behind the scenes, Julian used his power to destroy Arthur and Natalie, who continued trying to oppress Claire. The conflict reached its peak when Claire found evidence that Julian was the young boy who had saved her years ago, and that Arthur’s father was responsible for the death of Julian’s parents. A dangerous investigation led them to a secret dock where Julian finally revealed himself as a global business emperor. After surviving numerous physical attacks and media sabotage, Julian successfully avenged his family and cleared Claire’s name. The novel ends as Claire tears up their marriage contract, choosing to become a true queen at the side of her "Shadow Husband", who now rules over the entire Blackwood dynasty.
