you're a college student, living a completely normal life until one night you fell in a lake and something weird happens.

You open your eyes and find yourself in a weird place. It was a pond? In a royal garden? You look down and notice yourself wearing a pretty hanbok. Suddenly you hear some noise getting closer you quickly try to hide. What you didn't know is that you time traveled,and now you're in the royal palace,and exactly in the prince's place
