She was a princess born into silk and silence.
He was the orphaned boy pulled from the ashes of a ruined village.
Y/N is a princess forbidden from ever touching a weapon-but that doesn't stop her. Behind palace walls and late-night training sessions, she finds strength in secrecy... and in the smirking, silver-haired guard who teaches her everything her father won't.
Satoru Gojo is reckless, powerful, and always one step ahead-except when it comes to her. He jokes he'll marry her one day. Everyone laughs.
But only he knows the promise he's made to himself.
As curses rise and an ancient dragon awakens, their bond is tested by the weight of duty, the thrill of battle, and a love neither of them is allowed to speak aloud.
"A princess with a blade. A guard with a vow."
