The Command of the Army District

"If you don’t want to hand over a person, then hand over the money."

Junjinjin became an orphan after her parents died early. While staying temporarily with her maternal relatives, the Bang family, she goes to the Yeong family to honor an engagement contract her grandfather made long ago with Lord Yeong’s family. But when the Yeong family turns their back on her and tries to void the engagement as if it never existed, she tries to protest by pretending to hang herself—and accidentally loses her life for real.

Then another person, Choguryeong, is reborn in the body that has already stopped breathing...

She was originally Princess Guryeong, the daughter of the Crown Prince, who died of chronic illness three years ago. After learning the truth behind her father’s death, she tried to take revenge, only to be murdered in return, and was reborn into Junjinjin’s body.

Given this new chance, she resolves to pursue revenge and live on as "Junguguryeong."
