Ginorious Adolni, the fourth son of a minor viscount, carries the memories of a previous life on Earth. In that past existence, he lived for nearly a century and died completely alone, rejected by everyone due to his hideous appearance. Upon being reincarnated into a fantasy world of magic and noble society, his only true wish is to finally find a partner to share his life with.

That opportunity arrives through a shocking marriage proposal from the family of the premier duke. They offer him the hand of their daughter, Anastasia, but for a deeply unflattering reason. Nicknamed the Goblin Maiden, Anastasia suffers from a curse that gives her green skin, pointed ears, and a lumpy forehead, a monstrous appearance that has led to her being scorned and rejected by every previous suitor. While most nobles are repulsed, Ginorious sees his past self in her. He looks past her cursed form to discover a kind, intelligent, and genuinely beautiful soul, and resolves to use everything at his disposal including his knowledge from his past life to make her happy.

Their relationship is the heart of the story, beginning awkwardly but with a deep, mutual respect. As they grow closer, Ginorious realizes his past world was not the modern Earth we know, but a version steeped in advanced magic and golem technology. This knowledge allows him to understand that Anastasia’s curse is actually a result of her having dangerously excessive mana. While he works towards a cure, their bond gives her the strength to break out of her shell and confront the bullies at the royal academy who have tormented her for years.

However, their path to a happy ending is fraught with political schemes. After Ginorious successfully cures Anastasia’s condition, revealing her true beauty, the royal court becomes even more hostile. The first prince, seeking to consolidate power, tries to force the couple apart to marry Anastasia himself. He engineers a series of trials for them, including gifting them a failing territory to manage and ultimately sending Ginorious to fight in a pointless war.

The narrative arcs see the couple navigate intense personal doubts and communication breakdowns. A major conflict arises when Ginorious, plagued by insecurity from his past life, disastrously breaks off their engagement in a misguided attempt to protect her, leading to months of anguish before a reconciliation facilitated by therapy. Ultimately, the couple must confront the king himself. As Ginorious unlocks more of his past-life abilities as a golem engineer and Anastasia embraces her overwhelming magical power, she is finally named a living saint. The series concludes with the couple securing their peaceful future, having overcome royal plots, assassins, and their own inner demons to finally achieve their long-sought-after happily ever after.
