Kdrama like Nevertheless

Hello, I am looking for a drama as stated in the title similar to Nevertheless. I loved this kdrama, with the coldness of the ML, its acting and I especially liked the realistic side of the kdrama. If you have any recommendations for similar series with fairly mature characters, a toxic romance, a bit of incision on the part of the FL with a touch of reality. I'm not a big fan of comedy series so if we can avoid it that will be good.

I have already watched: - Vicenzo: my first kdrama. I didn't like it. Too comical in my opinion and not serious enough. The story drags on. - A Time called you: 2nd kdrama. I enjoyed it despite the twists and turns. I finished it in 1 day and I didn't sleep to finish it lol. The characters are endearing. I shed a tear at the end. - 20th century girl: 3rd kdrama. It wasn't bad. A light-hearted teenage love story without any fuss. - Nevertheless: 4th kdrama. Huge crush on this kdrama. I loved the storytelling. The toxicity between the two characters. Alchemy too. Maybe I shouldn't have watched it because now I'm only looking for dramas similar to it😭. - Love alarm: 5th kdrama. I didn't really like it despite the presence of Song Kang. I haven't even finished season 1. - Crash landind on you: 6th kdrama and I'm currently watching myself. I like the story. The comic side didn't bother me. I like Captain Ri's authoritarian side and the fact that he didn't hide his feelings. Currently I'm on episode 9.

My future viewings: my demon (with my favorite Song Kang), business proposal.

If you have any dramas to recommend that are or are similar to Nevertheless, I'm all ears.

PS: no matter the country, I am open to Japan, Korea, China, Taiwan.
