My Amazing Boyfriend- The FL is adorable and it can be pretty funny but it dragged like a bitch and had a terrible inconclusive ending. They changed all of the actors for the second season which really put me off, I wouldn't recommend jumping into it.
Master Devil Do Not Kiss Me- The male lead's a douche. Another case too where they changed the actors in the third season.
Princess Weiyoung- Scheming. So much scheming. Scheming to the point of it getting ridiculous. Also the one of the leads ends up unconscious every single episode. I swear my blood pressure has never been higher than when I was watching this show.
The Black Devil and the White Prince- Just bad. The acting, the story, everything was terribly cringey imo.
Here are my absolute must-watches.
The Story of Ming Lan- This is a realistic chinese historical drama set during the Song Dynasty. There are a lot of names, and ancient chinese sayings which can be a little confusing at first but it's totally worth it. This is the only drama I've ever rated 10/10. All of the actors are seasoned and it was made by one of the best production companies in China. It's definitely slow burn and there's not really any action but the dialogue is so incredible that even after 73 episodes I still wanted more. The female lead is so strong and intelligent without being obnoxious. The ending is extremely satisfying so I definitely recommend this.
A Love So Beautiful- It's the best school drama I've ever seen. Also it's on Netflix which is a plus.
Eternal Love- This is the most beloved c drama and for good reason. It's fantastic.
Goodbye My Princess- To preface, this is a tragedy. But it's such a beautiful journey with the most enchanting visuals and OST I've seen/heard in a drama. The ending had to be what it was and it would have felt wrong otherwise. I hate bad endings too, but this one was worth watching.
