If you want another stories don't hesitate to ask :)

My all-time-favourite author (The_storyteller) sadly got deactivated v.v but those stories are pretty good as well:

Silver Scales by voodoobaby (an Eunhae fic, I really love voodoobaby's stories ^^, it's about a boy from a small island who gets caught by pirates to help them find a treasure after they find out, that he's in fact a merman - sounds kinda boring when I write it, but it's well written and funny)

Warflower by ErisChaotica (a funny and beautifully written story based roughly on Mulan but set in Korea, with an OC as Mulan and Infinite as characters)
http://www.asianfanfics.com/story/view/181684/warflower-hoya-infinite-period-romance-sunggyu-supernatural-historical

Subject 310117 by chocolatemilk90 (a very detailed and long Eunhae fic - yes I like Eunhae - set in a postapocalyptic zombie world with Hyukjae as a commander of the military forces and Donghae as a test subject in a lab)
http://www.asianfanfics.com/story/view/531114/subject-310117-eunhae-supernatural-alternateuniverse

Dawn of the worlds by ReaLiknownot (the typical Exo plot with 12 Guardians, the tree of light and a girl to save them all - but the characters are awesome and really fun, the OC is neither the weak kid who needs protection nor the superhuman who kills all the enemies with a single blow, but a very natural and confused girl and at least I can identify myself easily with her :)

My Protector by BrightStar32 (A beautiful and sometimes sad Taoris story, where Kris is a dragon hiding in a cave and Tao finds him after nearly getting drowned)
