Same trope of cross dressing without the time travel. Splash splash love though is a movie and The Heiress is a tv drama with more complicated plot lines.

In Well Dominated love, Boss loved his chief secretary and married. In You are my destiny, Chen Jai Xin married Xi Yi and Jai Xin became the chairwomen's secretary. Also, these two dramas are separated from his partners.

Both movies share the theme of a woman being stuck on an island with a bunch of psycho dudes.

The synopsis is similar
like how they are showing students preparing for college entrance exam
The things the students and their parents go through

Both have Kim Seul Gi & Ahn Hyo Seop
Both are a short mini romcom
Both are lighthearted, silly, cute & funny

Both works involve the autistic patient...
both jo seung wo and oh jung se played that character in a phenomenal and beautiful way

Also, Love and Redemption is quite adventurous and good, because she's born without her six senses, she tries to regain them back, but one person is holding her back, so she would not regain her memories of her previous lives. Dance of the Sky Empire, there's also someone who erased the main leads memories so that he wouldn't be able to regain his memories, so the Jade emperor would not escape, and try to destroy the world.

They are similar, but yet so different, and I loved both shows.
Shockingly they were good and I would definitely recommend.

-Same actress FL with similar characters in both dramas
-Both dramas start with the characters together during childhood and then continue later as adults when they establish the relationship.
-Both MLs have to leave the FL suddenly for a few years, and later suddenly return, to start a romantic relationship. (Sounds melodramatic ik, give it a chance xD)
-Very similar premise and themes, but overall, With You is more of a fluffy romance, and Go Ahead focuses much more on family themes.
-Complex characters with more realistic issues and plot complications. (both slightly have slice of life themes.)

both about old couples with their problems ... and their tragic past
And their children's problems...

They are both horror/mystery/crime stories and have a similar dark vibe. They both deal with serial killings, even in the Children of Nobody take place in the present. But in both cases the answer is in the heroes'/heroines' past.

Both of them are horror/crime/mystery stories and both deal with serial killings, past crimes and the past of the protagonists.

- All the upright sects all think that demons are bad

- Not all demons are bad and not all good people are good.

- Male lead keeps sacrificing for female lead, while female lead does not know it.

- Male lead is very powerful

- Male recieves unrequited love

- Story is very interesting.

theyre not similar in tone or story etc, but they have the same lead actors. So if you liked their acting and chemistry then you might like this series.
