The FL in both dramas is Liang Jie
Both dramas have body swaps ( one between the ML and FL, the other one FL with the real body owner)
Both are really romantic and have great chemistry

Please come back Mister has body possession by two old ajussis who are reincarnated. They act weird and it's really fun to see them, yet The day of becoming You has no reincarnation but they swap bodies.

The only similarity between these two is the body swap
The stories are totally different and have different genres

Both dramas have Body Swap
The stories somewhat turn out to be funny for both leads
Big depicts the teenage side of being a different person, But the day of becoming you both are adults

They are very different in tone, but the underlying lessons about growing up and being in the closet are the same, and they both have the same bittersweet but cleansing ending.

both lead characters have distanced themselves from others and have a hearing problem, however they can surprisingly hear the voice of just one special person (*_________*)

Both MLs are the villains of stories (manga vs. novel) written by the FL who enter the real world. Both dramas have a similar fluffy romance tone.

Both dramas are a combination of the mystery, fantasy, and romance genres and involve a serial killer/kidnapper and the leads having a shared past experience together. Both couples end up living together when the FL is targeted so the ML can protect her and both MLs have a special ability relating to their senses (enhanced vision vs. hearing thoughts). Jin Han plays the ML in both dramas.

- both main characters goes through a series of injustice and hardships
- in 2037 the mother is impaired while in Miracle in Cell No. 7 the father is impaired
- creates a strong bond with their cellmates
- touches the sensitive issues about injustice around the world

- difference between these two is one is about a group of male living their life in jail while the other one is a group of female; one is a drama while the other is a movie
- main characters in both goes through a series of injustice and hardships
- both main characters end up in jail and creates a strong bond with their cellmates
- full of laughters and tears in both drama/film

Similar plot of friendship spanning multiple years, On your Wedding Day a little more comedic than serious compared to Close to Love

Both dramas center on the development of romance between a cold-attitude, warm-hearted ML and a dedicated, passionate FL who sees the best in everybody and is given the chance to explore another path in her career thanks to a project from the ML/her boss.

Both feature a prominent ex storyline, brief professional blunders, a foggy ML backstory that gets cleared up later in the story, a loving family, and a side romances featuring the ML's brother.

same vibes with same tyoe of suspense, thriller, murder and 3 main leads , story simlar linked with the past of the main leads,

if you like the voice Korean drama , you will enjoy this one also, same suspense, same type of thriller linked with a past.

Personally I find cutie pie similar to KINNPORSCHE in some ways for instance, the two dramas has its main characters not hiding or concealing their SEXUAL ORIENTATION and Infact the rest of the characters finds their relationship as being normal.
One could feel the originality and raw emotions between the two ML's and their supporting characters that brings us to make-believe. The STRONG RELATIONSHIP btw Kinn and Porsche , Lian and kuea regardless of the circumstances surrounding them makes the two dramas similar.
