Hi, my fellow 1990‘s child (or at least close). I‘m very glad that you are doing better now :D. As for 2019-2020 dramas, I have enjoyed quite a few of them, such as:
Romance is a Bonus Book - Best friends to lovers super sweet romance and very interesting work setting, almost slice of life-y.
Her Private Life - If you enjoy kpop, this will be funny/relatable as the lead is a kpop stan. Plus the leads have great chemistry.
Put Your Head On My Shoulder - I second the other users who recommended this.
A Little Thing Called First Love - High school / college romance. So many cute moments that made me smile. Just a heads up, leads are quite young actors, so this won’t be skinship galore.
Le Coup de Foudre - Another high school to adult romance. I’ll be honest, in the beginning it dragged for me, but I ended up loving it so much.
The Tale of Nokdu - If you enjoy historical romances, this one was great, funny, but also dramatic as the genre tends to be.
Search: WWW - If you are in the mood for something different. It still has great romance but it’s more about female empowerment and business conflict.
Touch Your Heart - Lee Dong Wook as a serious lawyer in a romance, yes please.
One Spring Night - I have a very soft spot for Jung Hae In haha. Also, this drama touched upon a social stigma in Korea that I had never seen in dramas before.
XX - Web series on youtube, but I was surprised at how good it was, really nice visuals, cute romance, but realistic and also not a long commitment to finish it.
Oh also, I haven’t seen these, but I know they are highly popular and recommended recent dramas: Crash Landing On You, When The Camellia Blooms, Itaewon Class and Hospital Playlist.
I‘m sure you’ll have a great time watching some dramas soon :D
