The Queen of the Warring States

A Ruo discovered that the new servant the household had hired was truly handsome, but he couldn't do this or that. Feeling she'd gotten a raw deal, A Ruo kept trying to make up for it in other ways. To everyone else, it looked like "The Evil Young Lady Bullies Her Loyal Servant."

Until one day, the loyal servant dropped his act and told A Ruo, "I'm actually the crown prince of a kingdom."

A Ruo: ...I want to run.

The crown prince dragged her back and showed her through hands-on experience that if he couldn't be a loyal servant, he could still be a loyal dog.
