There's an Exo #webelieveinyoukris story called Understood by Sweetsummer4763 that I really like. Also there are stories by vksujusnsd that I personally enjoy

Oddly enough, most of my favorite fics come from Infinite even though they aren't my bias group, but they do have really good writers so it makes sense I guess. You didn't mention what you felt about them, so I guess it's alright?
1. I Used to Have a Lover (who dreamed in Technicolor) - Sunggyu/Woohyun, Sunjong-centric
It's a great story to read if you're into the type where things unravel and pieces fall into place slowly but in a comfortable pace. It has that bitter, addictive thing to it that makes you just want to know more and just stay. I don't know, it's just really, really good.

2. the road that leads us there - Sunggyu/Woohyun
It has a very natural flow so it comes off as very realistic. It's both bitter and sweet at the same time, beautiful and tragic wrapped in one. It's like your first breath of fresh air. It's just. It's perfect.

3. rapsodia (the composition of us) - Sehun/Jongin
...it's pretty in ways that are hard to explain.

4. In Another World - Junsu/Changmin
Since you're in the dbsk fandom, I guess you've already read this but. I really, really like it.

I have to say we don't share OTPs so I don't know if my fics will suit your taste or whether you already read them yet. But if you're up to read about other pairings:

1. Pavlovian - action, romance, - kaisoo, baekyeol, hunhan
http://www.asianfanfics.com/story/view/382455
If you haven't read it: Whatever you think this story is about, you're wrong, that's all I can say. It's simply awesome.

2. The Agency - action, spy, romance - layhan, baekxing
http://www.asianfanfics.com/story/view/373081
There's a lot of side stories to go along too. Normally I don't read Layhan/Baekxing but it's good.

3. Mad World - sci-fi, romance - sekai, sulay, xiuhan, krisbaek
http://www.asianfanfics.com/story/view/445168
Since you put revolution, maybe you like sci-fi

4. anything written by curledupkitten, they're super long but it'll be worth of your time.

5. Broken Doll - romance, angst - Kaisoo, Krisho, Hunhan
http://flowerymisha.livejournal.com/30609.html
It's three parts with different protagonist each.

6. Shame That Nobody Ever Believes A Pink, Flower-Patterned Curtain - crack - xiuhan, chankai, krisdo, taohun, suchen
