The Strongest Crown Princess

She’s twenty-four inches tall and can eat ten buns at a time. Her favorite thing is riding on the Crown Prince’s back while eating buns. Don’t think that’s just a description of a tiny bun: it’s the heroine herself. You can’t judge by appearances. Who would have guessed that this little girl is the most formidable secret guard at the Crown Prince’s side? Year after year, the fresh-faced young man grows into a handsome middle-aged man, while the little girl remains a little girl. The Crown Prince is terribly dismayed. This girl never grows up, so how is he supposed to marry her?
