Definitely my kind of catnip. I guess it stems from the similarity to my drama kryptonite: enemies to lovers.

Chief Kim and Puppy Yul is another example for this ❤?

Another great catnip! I do see the recurring theme of how sometimes two characters who start out as enemies turn into allies at the end whether it is because they finally know the truth or their growing friendship. I typically like these type of turnouts and @nelly, I do agree that it is quite similar to one of my favorites too, enemies to lovers.

I'm a simple girl, I see City Hunter, I clicked

Love!!! Even if it's minor characters it still works it's magic on me too

This catnip is such a big one for me too! I'm also powerless in the face of the opposite -- estranged/broken friendships/sibling relationships.

I'm all for romance (or else why would I be watching so many dramas??) but so often the non-romantic relationships end up being just as -- or even more -- compelling.

Ooo. Not particularly catnip for me, I would say, but I do enjoy an enemies-to-grudging-friendship, especially if they really had no reason to hate each other (maybe a misunderstanding) in the first place. I enjoy watching them annoy each other and develop camaraderie. Plus I enjoy a good bromance. And like @nelly I also absolutely love enemies-to-lovers plots!

Honestly this reminds me of Hwarang, where Sammekjong and Sunwoo could have had a fantastic opponents-to-allies plot, but it just felt lacklustre.

JUNHO AND NAMGOONGMIN FROM CHIEFE KIM!! *___* My ultimate frenimies to allies couple bromance!

Gaksital and Oh Mok Dan. Swwwoooooon.

I'm here because of City Hunter?

I loved ghost! The plot, the ost. Um ki joon was soo good as the villain. Too bad the drama was underrated. I thought lee yeon hee did quite well in there.

I also like this catnip for the same reasons. A multi-faceted character is a much more interesting character. Characters evolving through the drama make the story feel more true to life. Those antagonists with one track motivations and one dimensional back stories are so dull even when the actor is frothing at the mouth trying to animate them.

Cruel/Heartless City had so much of those. It remains one of my faves :)

Chief Kim?? ... D to the O ??

I loved the first two examples.

It also helps that I enjoyed City Hunter overall and that I absolutely adored I Hear Your Voice.

I loved how in IHYV the two women weren't bickering about a man. There was no love triangle. And both were pretty headstrong. Also, Do Yeon is my favorite second lead female character. I loved how she redeemed herself, how much she grew, the decisions she made. It's part of what makes IHYV one of my favorite kdramas.

I definitely love this trope! I just finished Chief Kim and I was fist pumping the air when Chief Kim and Seo Yul finally worked together at the end. I could see them going towards that trajectory the whole drama and so when it finally happened it put a huge grin on my face (I could watch a whole drama focused on these 2 characters).

Don't get me started on Wild Romance ?

How about our most famous papa bear MDS and SJG in 38 Force unit?

I could contribute to that, besides "two weeks" i also love "Fugitive Plan B", it was cat-and-mouse until later when they agreed to work together

Goblin, anyone? Grim Reaper and Goblin were basically sworn enemies in episode 1, and then fighting Ghost Park together in episode 13 was SO SATISFYING, then Grim Reaper being the only one to remember Kim Shin when he came back from the dead--besides for Sunny (but she couldn't tell him)--was perfect poetry.

I'm loving these "Catnip" essays. Mainly because I didn't even realize I had "catnips." But every time I read one of these on Dramabeans I think, "this is my favorite." Then the next one appears in print and I think, "no. THIS is my favorite catnip."
WELL, this one here is my FAVORITE catnip.
I love enemies turning into friends. (How about Squad 38? The King 2 Hearts?)
And what I like the best is that while you're watching it, you wonder if the enemy really is a friend. Or if (s)he is going to be betrayed.

I hate it. But I love it.

ohhh I loved those two examples. City Hunter and IHYV <3

I liked CH-KJY partnership at the end, that scene you took was so exciting to watch OMG... KJY was an amazing character he had so much going on and to deal with, poor guy, work addited, catching a "bad" guy, dealing with corrupt politicians including his own father, threats, watching over Nana and his ex'wife. He could have his own drama.

in IHYV I loved those friendnemies girls.

Lee min ho x prosecutor, So Ji sub x Daniel Choi still kills me inside.
Love the badass ladies in I Hear Your Voice.
Ummm, can Lee Seung gi x Jo Jung suk be considered opponent to allies?
Still. Broken. Even after all these years.

I love this catnip! I hadn't thought of Wild Romance when you first said it, but Reporter Go teaming up with the main guys was so great, because it made him a much more complex character than just another drama reporter who only follows the money.

love this catnip so much--even more when it's two women becoming friends by the end of the show.

"I Can Hear Your Voice" has got to be one of my faves for this catnip =) A couple more that I am reminded of are "Secret" (the Ji Sung & Hwang Jung Eum drama, "Defendant" (inmate bromances ftw), "Heartless City" (although, this one is a bit brain-twisting because of all the undercover hijinks and not really knowing where everyone's allies are until THE VERY END. LITERALLY lol)

Not exactly my catnip, but its good to see the rival's character develop as they begin acknowledging our righteous leads.

I love this catnip.
School 2013 is filled with it.
Also in Legend of the blue sea, we have the detective guy up against Lee Min-ho and go on to become close friends...

Chief Kim and Yul comes to mind! I love their frenemy vibes throughout the show.

I haven't seen these dramas, but I do love this trope!

Chief Kim & Puppy Yul. My bestest frenemies. I squee whenever CK kiss Yul. Hahahahaha. They are just too awesome.
