Playful kiss is a kdrama version of it started with a kiss , Male lead is popular and very smart , the female lead is kinda dumb and chases after male lead even if he completely shows no interest in the start for a long time

Okay, hear me out.
-Both are romantic Kdramas.
-Charismatic, smooth MLs who fall in love first & pursue FLs.
-Strong FLs competent in career paths.
-Adorable second couples (with strong FLs as well)
-Both FLs struggle to commit to the relationship at first, but are eventually won over.
-Both dramas have the right amount of complication but also fluffiness (DOTS also has more action although side FL in WWW can fight hehe).
-Search: WWW is focused more on the FL, and other female characters than their love interests however.

Similar story-line: The hero(ine) travels into the past, and than stuck there...
In both you can find: timeless love, introduction of modern thinking and devices and funny moments.

Romance, stubborn Love. Relationship full of obstacles, challenging, up and down, painful love. Separation, jealousy, hardship, strong bond. Trust, truth, deep. Classic romantic Korean drama. Beautiful OST, beautiful casts, well layout, story of love between man and woman.

Both have the same director and are about low ranking samurai who deal with love, impending poverty, and honour.

-Same genres (comedy, travel, friendship, life)
-Lee Seung Gi's personality and looks never changed in many years
-Both shows give lots of laughter, very funny and enjoyable!

These dramas in my opinion had a similar vibe to them
* Bubbly ,vibrant and headstrong female lead
* Protective and lovable male lead
* Comical supporting characters
* In both the main leads are destined to be together
* supporting parents or parent
And overall if you enjoyed Melting me softly i'm pretty sure you'll like While you were sleeping :)
