Splash Splash Love

High school senior Jang Dan Bi (Kim Seul Gi) is dreading her college entrance exams – but on the day of the test, she literally splashes into a puddle and is transported to the Joseon Dynasty! There, she encounters King Lee Do (Yoon Du Jun), a young monarch struggling with mathematics, and a kingdom facing a severe drought. Mistaken for a eunuch, Dan Bi uses her modern-day knowledge to help the King, forming an unlikely bond. As their feelings for each other begin to grow, Dan Bi must decide whether to return to her own time, or stay in a past where she's found purpose and love.
