I don't really know if this story qualifies as , but it does include a steamy scene so I marked it as M just to be safe. But yeah, here's just a little 1200 word one shot:  http://www.asianfanfics.com/story/view/1115843/night-beside-a-shining-star-angst-friendship-oneshot-romance-you-exo-sehun

The description is: "Sehun is that bestfriend who is a bit too touchy and doesn’t correct people when they mistake you two for a couple"

It is also was my first time writing in second person, which was interesting. It's not as hard as I thought it to be and was a bit refreshing. But one shots are really easy and interesting to me so that's why I decided to just take an hour and write this up because I thought the idea was interesting and yeah, check it out and let me know what you think :)
