Dark Romance Drama

Hi, I'm looking for a drama somewhat similar to "Bridals Mask". I just started watching it but I (kind of) accidentally stumbled upon a spoiler... which.. kinda ruined my enjoyment ._. I'll still watch it though, since I love the story!

Anyway:

I'm looking for a drama where the couple experiences a lot of very tradigc/sad things together or maybe even alone and they slowly get closer to each other through that. Most importantly, by the end of the series it still ends happily and they are together (!). I don't mind characters dying, as long as it isn't the main couple and I DON'T want ambiguous endings where you don't know if they'll just be friends or more... :S

It would also be a very big plus if the female character is smart (mentally). She does not need to be physically strong (I prefer if the guy is the one...^^')

So far I'm REALLY enjoying Healer and You Who Came from the Stars, but they don't seem to be 'that dark'.

Innocent Man
That winter the wind blows

I second Secret - the heroine is a strong character who goes through many things. Really intense romance drama.

Check out MARS - not your typical good girl, bad boy drama as it first seems. One of the best romance dramas with a dark theme.

Autumn's Concerto is good too.
Long Love Letter - timetravel romance.

In Time With You, I Hear Your Voice and Smile, You - not really dark, but has strong female leads.

God's Gift fits too (heroine goes through lots of tragic things), but it's not a romance

Thank you so much for all of the recommendations - I'll be sure to check all of them out! ^_^ Just need to finish the dramas I've started already first xD

By the way, movies are fine as well :)

On a side note, just picked up Love Me if You Dare because the synopsis sounded like something I'd like + the good rating... and wow, it really does not disappoint! What I love is how smart (observant) both the female and the male character are.. Can only recommend it *-* 

I second Missing You. Also, try Tree of Heaven.

if you want dark romance, try byakuyakou (japan dorama), no dramas can't beat it :P

It's beautiful,  depressing, suspenseful with lot's of bittersweet moments. Masterfully well-crafted story till the very end.
