Two people who stumble into a marriage of convenience and slowly, without either of them planning it, start meaning it.

In private, the armor comes off, leaving two completely clueless teens desperately trying to navigate their first relationship. This chaotic balance makes their relationship one of the most unique couple dynamics in recent memory.

For her entire life, Miyo was reduced to less than nothing. Cruelly abused, constantly cast aside, and stripped of basic dignity by the very family meant to shield her. When she is arranged to marry a fierce military commander feared across the land, she prepares herself for the worst. But the monster she expects never shows up. Instead, she discovers a kind and protective man who is entirely opposite of the rumors surrounding his name.

Ikki Kurogane is labeled a complete failure. An F-rank and the worst student in his class in terms of magical ability. Stella, by contrast, is a princess and generational magical prodigy. Their journey begins when Ikki defeats her in a practice duel. Not with overwhelming magic but with a pure mastery of swordsmanship born entirely from relentless, grueling hard work. What sets this series apart is its refusal to rely on the standard romance clichés; it establishes them as a couple early on and then tests their bond under immense, real-world pressure.
