Korean (and other) dramas without (with no) love triangles!

There are two guys falling for the same girl. But it does not end like usual. And they care more about their revenge and personal business rather than love.

Watched this one many years ago but the plot was so good that I don't remember they even needed an annoying triangle.

Spoiler............................. 

His son likes the girl too but love is not even something you end up having feelings about, You understand that the feeling of all three of them is not even about love. it's about friendship and regrets.

A good drama and without a love triangle.

As much as I can remember there was no love triangle.

No love triangle.

This one may be a little tricky, but the love triangle is not annoying at all since there is an element of surprise. This one is really good.

A girl likes the male lead, but it is just a means to tease her family, and that doesn't last long, and the story is good enough that they don't need a triangle.

The second lead has his chance.

It has a love triangle but the girl does not even know who she favors and it doesn't end like the usual.

A really good show

Dropped this one. But it does not have a love triangle

If you're interested in science fiction. There is not a love triangle worth mentioning. Perhaps 5 minutes of all the episodes.

The genre is a crime and not romance. There are very few moments suggesting a kind of love rivalry, but to be honest, as a hater of triangles, I didn't mind at all. 

It has a love triangle but I really didn't want them to end up together and the main couple is really sweet in my opinion that you don't really care about anyone else.

The fact that I don't remember if there was a strong focus on the triangle means it didn't bother me.

There is a triangle but if it doesn't have more than one episode screentime I don't consider it an annoying triangle.

I haven't watched this, but two people suggested it does not have a triangle.

I honestly don't remember a triangle with this ( at least it was not strong enough, or taking a lot of screentime ). I really liked the story.

I dropped this one, but two people suggested it doesn't have a triangle, so watch this at your own risk. 

I also dropped this, but two people suggested it does not have a triangle. There was an episode with past lovers in total 6 episodes that I watched, so watch it at your own risk.

It was suggested to me by a few people. I also dropped this one. So watch at your own risk.

There are others who love the main leads but don't take more than one or two episodes.
