Secret
Innocent Man

Your new to drama land! Welcome!

I love sad dramas. Here are my favorites~
(This list is in order from best dramas to worst, though none of them are bad. Numbers are tearjerker ratings 1-5. 5 being most tears)

2 It's Okay, That's Love- It's sad through out but only a few tears for this one. 
4 Cruel City- The drama is about the underground. Cry at the beginning, cry in the middle, and cry in the end. The emotions are super high.
5 Ouroboros- My all time favorite Japanese Drama. Check it out :)
5 49 Days- It's a weepy one. Definetly one of the saddest dramas out there. 
5 Mama- Winner for tearjerking. I cried the entire time. Seriously. I just didn't stop, through all 24 episodes.
4 Scent of a Woman- while it is meant to be sad, its also meant to be happy, and it melds the two rather well.
2 Secret Garden- This has one of my all time favorite sad scenes. 
4 Super Daddy Yeol- It was cute, and decent. Watch the others first!!

Also I don't think Innocent Man is all that sad, BUT it is my all time favorite drama, you should definitely watch it!

If you need more just message me! I'm always on MDL :)

second 1 Liter Tears - it makes you cry like every episode but it's about sickness
What Happened In Bali - it's sad/depressing and made me cry on the last episode-twice since I re watched it.
Que Sera Sera

Proposal Daisakusen << my favorite

90 Days of Love << this is 6.6 but probably cuz its about first cousins and death so maybe not

Sang Doo, Let's Go To School
Delightful Girl, Choon Hyang
Full House
Full House thai version

Rent a Girlfriend Home for New Year << not 100% sure about this
Save the Last Dance for Me

Hormones/Hormones 2 << this show is more realistic so it has some sad moments

I'm a bit all over the place when it comes to dramas so i'll recommend some of my fav's from each country:

Korean:
I Hear Your Voice - is one of my favorites that mixes comedy and really heavy moments well. You'll laugh just as much as you'll cry. I was doing both at the same time by the end!
Secret - The only TRUE melodrama I've seen that has left me speechless
Thank You - Nothing but tears as it involves a cute sick child ;'-(

Japanese:
Koizora - There's a drama and a series, I've seen both and you really can't go wrong either way

China:
Scarlet Heart - Historical tearjerker. Oh the feels

Taiwan: Summer's Desire - it's 2 hours per episode with a total of 14 episodes.It involves a twisted love triangle, so depending on who you're rooting for you can love it or hate it.

Have you seen 'Sad love story'? It's my fav drama of all time, and well, the title says it all :) It's from 2005 so it's pretty old, but it's definitely worth the watch!!!
