Enter Carnelia Easter, the awful secondary villainess of the romance I’m reading, who trapped the prince in marriage at the behest of the evil empress. I didn’t shed a tear when her head was lopped off, but now I'm Carnelia! I gotta play this smart and convince him to divorce me instead! Still, between the prince, the empress, the heroine, the second prince, my terrible health... this story’s getting unpredictable. Will I survive after all?
