Recommendations

Both dramas deal about girls that are getting bullied and have something happen to them because of this. In both dramas family members take revenge and things become very fast very extreme.

Both of these are time travel and includes Scifi and there is no romance. Both dramas include action. Of course, they are definitely both really interesting!

Both are critically acclaimed thriller movies by Bong Joon Ho and Song Kang Ho plays a main character in both.

Both are thriller movies by Bong Joon Ho that show violent detectives that are abusive during interrigation, feature a character with a disability (in Mother its the mc and in Memories of Murder a side character) who is accused of being the murderer of (a) girl(s). They leave you guessing till the end.

Group of youngsters get together in order to solve mysteries. In YB they are 6 while in MH have 5. Adventurous series in costume that worth watching. Satisfactory romance in both. Young Blood's end is open, though .
Stong, wise and competent female leads

Both series involve 2 male leads who try and save a bankrupt/corrupt company,

The biggest difference would be that in Chief Kim, the male leads go from enemies to friends while in A2A, they remain friends all throughout. Chief Kim also has a more comedic tone while A2A is straight business and finance.

Both have a great story about business and finance, as well as a good bromance.

My first first love 2 is the sequel and also the continuation of the the Kdrama My First First Love. If you enjoyed watching this drama then you will also like to know what is going to happen in its next sequel.

They're very similar
1. Both ML are Vengeful towards the FL because of Misunderstanding.
2. The Plot is very similar the difference only in Kluen Cheewit Sathit's Lover Died but in Lhong Ngao Jun Thanakim's Friend Died.
3. Both ML's have many similarities in terms of personality
You will feel like you're watching only the same Drama

Both are high school romcoms with an unconventional feel and good cinematography. Both feature love triangles with a quirky female lead.

True Beauty hasn't finished yet at the time of my recommendation, but it primarily deals with the idea of beauty. Both protagonists are 'ugly' (not really) and receive ridicule for their appearances. They endearing character prevails and allows the love interest(s) to fall in love with them despite their appearances.

both have the classic friends to lovers trope and the same leads having 'something' for each other but not confessing because their current friendship might be jeopardized. i dont really know how to explain it but the male leads of both are very similar according to me

the stories are verry similar and the ml is the same actor (Lee Joon-gi). i highly recommend this drama

Both have two male leads who have a (somewhat) close relationship but are opposites when it comes to their morals. One character is more involved with the underworld while the other character is a righteous police officer, meaning they butt heads frequently but still work well together.

Both dramas have that same gritty feel to them and are focussed on crime.

dear m is based on this show. the show hasnt been released yet so idk how similar they will be but dear m is based off of love playlist so they should be similar!

both FL
*are quick-thinking, intelligent forensic scientists
*are struggling with an unjust parental death
*are pursued by good men with their own personal/political intrigues
*are repeatedly in danger because of a larger power struggle

in both:
*1 ML has government affiliation, 1 ML has ties to the "dark" side
*each ML is embroiled in a much larger struggle for power

context is historic China and issues of gender equity/plight of women are explored (more in MH than MT)
