Kigen-tsuki Koujo no Hazu ga, Umaku Yari Sugite Shimatta You desu

When a humble village girl named Freya crosses paths with her exact doppelgänger in town, she never imagines the encounter will upend her life entirely. The stranger turns out to be a runaway princess, and through a bizarre twist of fate, Freya is thrust into the royal palace as her unwilling stand-in. Trapped within the castle walls, she faces a terrifying reality: if her true identity is ever exposed, it means certain death. Desperate to survive, she commits herself fully to the dangerous charade of royalty. However, stepping into the princess’s shoes quickly reveals the grim truth behind the crown. Freya discovers a deeply hostile environment shaped by a neglectful emperor father, an apathetic fiancé, and malicious maids who scheme against her at every turn. Rather than succumbing to despair, she realizes that the only way to lure the real princess back—and secure her own freedom—is to transform this toxic household from the inside out. Armed with her natural grit and unwavering optimism, Freya resolves to defy the scorn of those who dismiss her as an incompetent royal, determined to rewrite the tragic circumstances of the life she was forced to borrow.
