A Villain Who Can't Fall in Love Is No Good Boss

My life is just so miserable... I'm a prince and clearly a villain, yet my country was destroyed, so I never got to become king. The Queen of Beirong has sent her female subordinates to hunt me down to the ends of the earth. I can't even flirt with girls on the run, in case I accidentally get myself killed trying to pick someone up. And the only thing keeping me going, my little sister, isn't even my real sister... Hm? Wait a second. Isn't that great?
