When you look at my watchlist, you will see that I have watched many dramas. This is why it is hard for me to find something new that could trully coutch my attention. "Hate to love" is one my favourite themes and I will be most gratefull for recomendations.

Examples of hate to love dramas that I liked:

Family's Honor - my all time favourite

Secret 

Falling for Innocence 

Hotel King 

General and I 

Hana Yori Dango 

That's also my favorite trope!

A love to kill (2005) -> (Kdrama) I checked your list and I don't think is there. One of my favorite of this kind of dramas.

Kleun Cheewit (2017) -> (Lakorn) I don't know if you also like lakorns, but this is the perfect one for what you are looking for

Hua Jai Sila (2019) -> (Lakorn) You should give it a try. Revenge and love

Like you wrote, you've watched already a lot of dramas of this genre, therefore it's hard to find others. I hope someone else can also add something!

I watch dramas from Korea, Japan, China and Taiwan but I have never seen any Lakorn (only F4 Thailand, which was nice). I was thinking about trying lakorns, so I will start with your recommendation. Thak you.

My Name (not a romance drama tho)

You’ve probably heard of it or watched before but I’ll recommend them anyway: The Princess’ Man, Bridal Mask, Goodbye My Princess (well it’s more convoluted than hate to love but the gist is still there), Kleun Cheewit (+1, and honestly like all of Mark’s dramas)

Not really pure hatred - more like skepticism/dislike to love: Battle of Changsha, Skate into Love, 100 Days My Prince (the latter two couldn’t differ more greatly in tone to Changsha which gets very, very dark so be advised)

If you’re open to Turkish dramas too my favorite use of this trope is actually in Vatanim Sensin (I think it’s called Wounded Love in Eng). You could really enjoy Hercai too if you’re fine with a good dose of sexism. Fatmagül'ün Suçu Ne? is also a classic of this trope. All of these are well known enough to have eng subs available.
