A princess is kidnapped by an evil dragon, and a hero challenges the dragon in an attempt to save her, but...
The princess was once the strongest Demon King of her era, and the dragon who kidnapped her is one of her favorite adopted sons, her beloved boy.
The female hero is actually the childhood sweetheart and fiancée of that beloved boy, as well as the Demon King's own daughter.
The engaged couple start fighting right in front of the princess over their dear old dad!?
Dragon Kai: "I'm calling off the engagement! I'm going after my true happiness!"
Hero Fran: "Don't you dare touch her! She's my dad!"
Hey, she's not wrong.
Princess Phil had planned to do her duty as their dear old dad and help the bickering young couple make up... but her beloved boy just keeps getting more handsome, and she's starting to find him rather appealing?
Hero Fran: "Dad, what are you doing? He's my husband!"
Princess Phil: "What's wrong with Dad having a little fun with your husband? Do you even know what filial piety means, daughter? Keep complaining and I won't spare you either, you hear!"
