I've seen 100+ Asian dramas but I'm not currently going to add them to my watched list. Compiling a PTW is my main priority for now :D
I love dramas that get you emotionally invested and drag your heart and your feelings along with the plot.
I did however get hit a bit too hard with Ouroboros and 1 litre of tears ;_; they were both so tough. I wanted 1 literally of tears around 2011-2012 but Ouroboros recently so that is why I used it as an example (since it's more recent. Illness related dramas are strictly a no go for me now because they hit too close to home).
My favourite genres are:
J-drama - Mystery/crime/detective
K-drama - Historical, Historical-mystery, melodramas like king of baking, Kim tak gu
& I love food related dramas from any country.
I used to watch 15+ dramas at a time and follow airing shows for a few years but that caused a slump and I didn't end up watching any dramas for 3 years. From now on I'll only watch 1 show at a time.
