Very similar storyline about a rich woman with a high status and a poor ordinary man. Watching Takane no Hana was very nostalgic and brought back fond memories of when I watched Celeb to Binbo Taro many years ago.

Whilst I was watching CLOY I kept being reminded of Faith. Has a similar storyline - FL ends up in a place where she doesn't belong, and ML - a military leader ends up protecting her, falling in love and trying to send her back to where she belongs

Similar story. Romance between South Korean and North Korean. If you prefer a more action packed version of CLOY then watch Korean Peninsula

Similar theme about vulnerable children being abused, injustice & the struggles of them & those around them. Word of caution: Silenced is much darker than Children of Nobody, dealing with sexual abuse and contains more explicit scenes.

Similar theme about abused children, those around them & the struggles they go through to overcome the trauma they have experienced.

Similar vibe. Lead has special ability that helps with solving crimes. Watching While You Were Sleeping reminded me of The Girl Who Sees Scents

Similar storyline. Ordinary guy - Postal worker (That Fool), water delivery guy (Mr Duke), is asked by celebrity/rich heiress to pose as their boyfriend/fiancee. Both male leads are nice guys

Roles are kind of reversed, the guy chases after the girl in From Five to Nine. Gives off similar vibes. If you liked one you'll most likely like the other!

Similar storyline - female lead has a car accident & is given a second chance to live again but has to first live as somebody else

Both drama's are about an individual from a non-political background who eventually runs for President driven by personal tragedies and circumstances in order to establish a better society.

Similar base story about working towards the unification of North and South Korea. As One does this though sports, Korean Peninsula through engineering and politics.

Similar storyline. Wife loses memory, only remembering her childhood/ young adult years. Her husband is left to try and make her remember their life together and get her to come back to him.
