Dramas with Enemies to lovers like Crazy Love

Hi there. I am looking for dramas with an enemies to lovers trope with a brooding ML that’s not rom/com fluffy.

I’m very new to k dramas, having only started two weeks ago. It started with xo kitty and the cute enemies to lovers relationship between kitty and min-ho that lead to Netflix suggesting business proposal. Business proposal was entertaining and light hearted, I enjoyed it for what it was although at times really over the top and cheesy—I enjoyed the possessive male lead/ social class difference/ and slow burn. After that l watched Crazy Love. I was instantly obsessed. The plot was good, the chemistry between the leads were great and I am a sucker for a brooding/jerk male lead who eventually falls for the female lead.

I’ve been trying to chase the high of Crazy love ever since. I watched 4 episodes of Love to Hate you and could not stand the FL I found her so cringey and over the top. I watched 9 episodes of Her private life and as much as I liked both leads the story just fell flat to me where I pretty much fast forward through the story besides their scenes. I then tried What’s wrong with secretary kim and same thing. 8 episodes in and the plot is too stretched out I’m getting bored.

Please recommend dramas with a mature (age 30+) ML who’s attractive, rude-maybe even dangerous, who has no interest in the girl at first so the romance is a slow burn.

Bonus points if the show has a more in depth story/darker and less fluffy.

Please help me get my next enemies to lovers fix.
