Splash Splash LOVE (2015)

Female leads are highschoolers, who have no interests in studies before time-traveling in the past. The atmosphere is light-hearted and funny. Both have cute and fluffy romance with female leads hiding their gender. While one drama is Japanese, the other is Korean.

Both are mini dramas with a modern day FL who finds herself in history.

Water always is the mystery entity.... for SSL it's time travel and for LotBS is memories. In a sense, they're both time travel and show how love has no time but overall they have the same comedic feeling and "foreigner" trying to get accustomed to life in a new world.

Both are mini dramas with a modern day FL who finds herself in history.

Both include time travel and a sweet romance. Splash splash love is a movie while someday or one day is a drama.

Time travel results in romance between ML and FL. Similar tone, especially in the lighter moments. Scenes set in past and present.

Both are mini dramas with a modern day FL who is magically transported to historical times where she meets and falls in love with the ML.

Tho splash splash is kdrama set in historical drama, the time travel component is present..the short length sweet series aesthetic is the same in both..

Both FL like King in other world. Time travel is involved in Splash Splash Love. Parallel world hopping in The king: Eternal Monarch. Both couples are cute. Splash splash live is a short carefree drama while The king eternal monarch is a 16 episode drama.

Though not as a much of a gem as Splash Splash Love - in my personal opinion - Snow Lotus still managed to touch my heart in a similar way by covering two of the same themes: love, and the blending of the Joseon era with modern day. It's also only two episodes long.

it is kinda similar in plot but to be honest I don't know why, I just kind of got that kdrama 'Splash Splash Love' vibes from watching it.
