× starts out by both leads hating each other.
× in both dramas the main leads are some kind of famous
× main leads have to pretend being in a relationship
× the best friend of both female leads are similar.

Both are Older woman-Younger man, living together, falling in love without realising, being friends first... both are great and lovely all the way through ?

this is another "recommendation doesn't mean similar", but both have a slow healing process and the main guy in Nobody Knows is also a teacher and some of the plot happens in a school

based on Nobody Knows's premier it looks like the plot is surrounded around cults and it gives off the same vibes as Save Me.

Both are crime dramas that give off the same feel as far as the crime and suspense go. They also both feature recreation memories, and detective work.

The drama The Wonder Woman gives the same vibes as Search WWW from it's very begining :
- A cold sucessfull Businsess Woman
- ML falls for FML first
- about business crises resolution and reaching the top

I would say GTO is much better quality. You can watch any GTO anime or series. Both are about right and wrong.. and daily life situations. even though settings and plot is different, main ides stay kind of the same in both dramas.

Both about solving mysteries and helping the state
Both FL and ML involved in solving mysteries
Both FL and ML don't get on initially

-Love triangle
-FL forced into marriage with ML
-FL loves the 2nd male lead who although loves her but doesn't sacrifice as much for her as the ML
-FL and ML don't get on at all and wishes to run -away with the second male lead initially
-Both 2nd male leads have other identities making it difficult for him to put the FL above all else unlike the ML in both dramas

my memory is kinda foggy on the details, but I believe both had the same "corruption/hiding the truth/giving out fake news and making others look guilty...

both male leads were really similar in characteristics and their drive to success. both worked hard from the bottom trying to achieve their dreams, and in some ways both did want revenge xD

Main male leads have a similar past, and they are both known under an ugly name connected to their past. Investigative, murders, torture and disturbing cases.

Spoiler:
Both have kind a strange ending (much more Voice 3 but still.)
Similar vibes, overall

I am such a huge fan of Hello Monster and have been looking for bright police procedural kdramas like this for years (as in not dark like OCN police shows such as Voice), and this is a must watch! They have similarities in such the main leads are connected through a childhood trauma, and they both meet again for revenge purposes. Enjoy!

The main lead dies and returns again not having aged a day old from when they left. The leads try and figure out what happened leading up to their death and try to fix what they can.

Tunnel and thesus no fune have many similarities which become more evident as the the drama progresses..time travel is the main theme in both of them..and importance of family bonds is strongly emphasized ..with the family members willing to do anything to protect their family.Both share beautiful plot and amazing acting.
