So I'm one of those people who enjoys the death or pain of the female lead lol. In Kdramas it always seems to happen to male, so I get bored of it. So does anyone know any asian dramas where the girl gets stabbed or gets some serious disease or something, or she dies at the end?

lol...:D well then..

Beautiful Life (J-drama) -----this was good :)
49 days (K-drama) ------> loved this ^_^
Seijo (J-drama) -------> It was ok. Not really fond of it but check it out if you like :) just 7 eps so..
Jin Jin (K-drama special) ------> loved it!
Culprit Among Friends (K-drama special) ------> liked this too

If you don't mind some movies as well :

A Moment to Remember (K-movie)
A Company Man (K-movie)
Rainbow Eyes (K-movie) ----> this is a bit mature though!!
Steel Cold Winter (K-movie)
You and Me (J-movie) ------> If you consider the female cat as the main female lead :D :P
1 Litre of Tears (J-movie)
Knowing that something bad will happen to the female lead can be an enormous spoiler though haha I also recommend 49 Days, it left a deep impression on me .
Marriage contract
1 litre of tears
Bad couple
Stairway to heaven

Scent of a woman is a good drama~
All About My Mom (but she's an Ahjumma/elderly lady)
