Dramas: She is lovable, What is love, Say that you love me, Emergency couple, Fated to love you, I miss you, Will it snow for Christmas, Boys Over Flowers...

Korean movies have a difference, you never know what will happen. So correctly, you are right, usually the main character always dies

The korean film ingrained in my mind that the characters will be leukemia,cancer.. and then die.Generally,It often take away more tears from the audience.I was impressed by a moive I've seen since childhood is "Giay Thuy Tinh" and of course the main male character dies.

I like Korean films too. I know some website in Vietnam can help you seeing more films. Do you want to take it?
