Scarlet Heart Ryeo hands down!!!!!! My tears still won't stop sigh:/
Scarlet Heart Ryeo, Missing you and Fated to Love you.
Fated to Love you starts out with funny and romantic moments, however, it then turns into a tear jerking melodrama.
Missing You is heartbreaking from the start. It's twisted and cruel.
Unlike the other two, Scarlet Heart Ryeo, leaves you heartbroken and in despair because of the ending. Even though the episodes in the beginning were a bit lighthearted, you could sense the underlining darkness that some characters and events portray. Each episode had its nice and sad moments, but the last 5 or so episodes were all so sad that you wouldn't stop crying.

I usually re-watch my favourite dramas, but unlike the rest, Missing you and Scarlet Heart Ryeo are probably the only two dramas that I can't bare to watch again even though I really love them. I'm the type of person that enjoys laughing, crying, screeching, fan girling, yelling and getting angry because of the characters and story, but with those two dramas I don't think I ever will have the ability to withstand all the heartache and tears that come along with watching them again.
Just get ready for tissues coz you will cry so much.
1. 1 litre of tears--- really, I think I cried bucket of tears
2. Stairway to Heaven-- one of my favorites
3. Chuno----You will love Daegil w/ your eyes swollen
Scent of a Woman the leading lady's crying emits sadness

The Master's Sun yes, ghosts' stories will make you cry your heart out
