Brinny and the empty seat

A story about a possessor in a book who would even commit murder to achieve their goals.

Brinny, who lived in compliance with her stepfather, thought it was something that had nothing to do with her—until she got entangled in an incident with the sickly 2nd Prince, Lucian.

In a moment of crisis, Brinny uses her immense strength to save Lucian and feels relieved when she sees that the possessor ‘Aridna’ has been captured, believing everything has been resolved.

But somehow, her beloved sister and the 1st Prince die in a carriage accident, and afterwards, even her now-fiancé Lucian starts acting strangely.

Wasn’t the possessor executed in the past?
Could ‘Aridna’ still be alive?
Determined to fill the void left by her lost loved ones, Brinny makes up her mind.

She will fight against the possessor.
