What story does Roman Holiday tell?

The story tells a romantic story between a princess of a principality in Europe and an American journalist in Rome, Italy, in one day.

Princess Anne, who was tired of royal life, traveled privately during her visit to Rome and met the American journalist Joe. Joe and photographer Erbin colluded to sneak a lot of wonderful shots of the princess to prepare for a special report. Unexpectedly, I fell in love with the princess. In order to protect the image of the princess, I was able to reluctantly give up the chance of success and send photos to the princess as a souvenir. Princess Anne didn't want to be at the mercy of royal etiquette, but after a day's holiday in Rome, she realized her responsibility to the country and reluctantly returned to the embassy to express her thoughts decisively.
