Splash Splash Love (2015)

They are both time traveler from modern day to help out the King in the past.

Although both are kinda over the top but the Journey to Tang is a bit (very) unrealistic compared to Splash x2 Love. They are both fun and amusing for a short movie/drama~

Same girl dresses as eunuch and falls in love with the emperor storyline. The only difference is that Splash Splash Love has time travel genre.

Both of them are about to take an exam and was transported to the past and learned something about history
