Tree of Heaven (K-drama) Silence (T-drama)
I'm Sorry I Love 1 Litre of Tears
49 Days It's so sad but I love it and still re-watch it
1 Litre of Tears. I still consider it the only must watch drama.
I was not going to say Autumn Tale/Autumn in My Heart, but seeing all the other posts mentioning that one reminded me how sad it was.
Gumiho: Tale of a Fox's Child. odd, I know, but an innocent, sweet child being targeted that much, well, I cried over this drama more than any others that I've seen.
I still have not watched a drama that matches the level of sadness I felt while watching 1 Litre of Tears.


Dear, everyone. Please don't post spoilers in here. If you do need to post one, PLEASE use white font so that you don't ruin a drama for somebody by giving away important plot points.
definetly 1 Litre of tears.
King2Hearts - One of the saddest dramas ever. Not usually a big crier but I got so emotional even weeks after it ended.
my #1 is Empress Ki for sure , I was paralyzed by the events for weeks even after I finished it.

1 Litre of Tears, Mask, Boku no ita jikan , 49 Days are all amazing yet so sad dramas (all managed to make me sobbing)
Six Flying Dragon, Orthro no Inu , Secret , Lipstick are also 2nd of the list (all are amazing and a somehow sad drama)
Autumn Tale
Tree of heaven
1 liter of tears
Taiyou no Uta 
If in Love Like Them
The Hours of My Life with Miura Haruma....That was so devastating!
