they give me the same vibes, like the both main characters are in love with an fictional character.

childhood friend
one becomes the manager of the other who has become a star
Love triangle
Ennemies to lovers

ML can see ghosts and makes relationships with the ghosts. In Showtime, ML has a give and take relationship with the ghosts while in Ghost Doc, ML is really only giving help to the ghosts.

Both explore similar themes of social hierarchy and the prejudices incurred. Parasite however is more in your face and High and Low is more subtle. They're both directed by the finest of directors to ever exist and definitely a must watch!

Its about an older woman with a younger guy. Its not a love hate relationship but she is just not interested at first. Also problems with the family because of the age gab. This drama is adorable, never gets boring, i totally recommend it to you

Not so much the serious action movie but as a series it is also about punishing and fighting "bad guys" with drastic measures.

Both has the same theme about Start-up a new idea, project, company and then make big. Both has dream, team work, supportive friends, great idea, hard work, faces harsh challenges. Young enthusiastic people.

Both dramas are similar in the aspect of ghost seeing, supernatural elements and ghosts staying back instead of crossing over to protect their child. Even after death the main leads who are dead and now ghosts stay back on earth and protect their daughter from harm and resolve their regret.
The difference is in "Hi Bye, Mama !" the female main lead a.k.a mom ghost gets the opportunity to become human for 49 days and accompany her daughter whereas in "Who are you?" the dad ghost can possess the male main lead and help his daughter from behind the scenes without telling her that he is the ghost of dead dad who possessed the male main lead.

both are bls with some phenomenal angst, gang activity, amazing action scenes, and great actors. same general crime aura—but while Not Me is more social justice, Long Time No See focuses on the criminal underworld; however, they’re both really good for many of the same reasons!

A female returns to a place she used to belong for the sake of uncovering the evildoer behind the killing of her relative, but is reluctant to fell in love with the main male protagonist as he might have been involved in her case.
One of the people in it suffered from amnesia for a long period of time (years) and can't remember important clues.

The second female lead is incredibly suspicious as being the evildoer.

The female protagonist returns to the place of her relatives suicide to take revenge on the people, who took advantage of that person and pushed him towards his death. She disguises herself at the beginning. The male protagonist might be involved in her case so she is being not-so-close to him..
The real evildoer is somebody very close and somebody who had always been very helpful to her.
The second male lead is an antagonist.

Both have:

- a female protagonist with painful past;
- a male protagonist, which works against her...
- a second male lead who suffers from mental illness, but is a very kind and gentle person;.. and another one who looks just like him, but it's a psychopat.. /identical people... Both suspected of being behind a series of murders/
-a murder case, which killer isn't revealed until the very end
- the male lead always tries to protect everyone

A relative of one of the protagonists is the suspected mastermind of a killing of the other protagonist's relative. Both are beloved relatives of the protagonists and their killings and/or disappearances caused a lot of mental trauma.
A couple has to reveal a killer and deal with the concequesnces of that reveal.. as it might.. prevent it from being together.

Both are MBS BL drama. Good quality Jdrama even though the genre is far from each other since Fukokiss is fluff romcom while Utsukare is more on the serious coming of age tone.

Both are melodramas with similar pacing and moody atmospheres. Also, both are slice-of-life dramas that focus on character relationships over eventful plots.
