Maybe watching dramas from different country will help. If you usually watch kdramas maybe you should try watching Chinese or Thai dramas. I'm doing this right now and it feels fresh and I'm feeling like I'm discovering something new but at the other hand Chinese dramas are not totally different from kdramas. Thai dramas have more differences but they are also fun.
From what I have watched, here are some interesting C-dramas and Thai dramas:
Good Bye My Princess
Siege in Fog- I am still watching it but it's really good so far
Boss and Me- almost like kdrama
Hua Jai Sila - it's a little bit dragging at the end but it's a good watch mainly because of the ML
Cheewit Puer Kah Huajai Puer Tur
Here are some kdramas that are addicting till the end:
W
You're Beautiful
Coffee Prince
Strong Woman Do Bong Soon
Empress Ki
Kill It
Goblin
Good Doctor
Sungkyunkwan Scandal
My Girl
