Hi

Does it exist any Gay K-Dramas? I was wondering about that. I hope so. Would be cool to see.

There probably are a few but I haven't watched any. I think you might enjoy Love Sick: The Series (2014) even though it's Thai ^^
Come on, Reply 1997 can in no way be classified as a 'gay' drama. It featured a gay character who barely had a story line. Moreover, there wasn't any relationship (of a romantic variety) in progress for you to say 'they didn't end up together'. Your comment is very misleading.
Ouch, spoilers.

I'd recommend Life Is Beautiful which has an actual main gay storyline.

Helpful links in this thread. :)
Perhaps i must look after dramas with strong Bromance?
Not dramas, but movies that I've watched and I recommend them:
Antique Bakery

Just Friends?
No Regret
Two Weddings and a Funeral

Not a gay movie, but the male main character want to be female:
Man on High Heels
Ho Goo's Love - one of the main leads thinks he's gay and even though it's all a misunderstanding, he doesn't realise that until close to the ending xD
The lover is about four different couples living together in one apartment complex. One of the couples is gay couple!
Thanks. The problem is that i want to watch a drama, not a film. I appericiate the suggestions. It's strange they haven't made more gay dramas. Is touchy subject in South Korea?
If you want strong bromance, I recommend School 2013, Reply 1997, REply 1994, A Gentleman's Dignity, Coffee Prince
The lover is drama...
@Helena I agree that a gay relationship in The Lover is being hinted and the ending is very open for interpretation.

However, if the person is looking for a gay drama only, then they would find The Lover boring and/or dragged out because it skips between the couples really frequently and focuses the most on Oh Do Shi/Ryu Du Ri, while leaving very little screen time for the actual gay couple.

That's why I think The Lover will not be too suitable to be called a 'gay drama'.
Simona, that's what i thought. I will concentrate on dramas with bromance then. I have already bought School 2013, I will buy Coffee Prince next time later this month.
