^My personal favourite, I rarely read Baekhyun fics.

Baekhyun is beautiful c:

This can help if you're having trouble scouring through Baekhyun fics

I don't know if this will be your cup of tea but this is my third time re-reading this story: http://www.asianfanfics.com/story/view/426081/the-marriage-life-of-mr-byun-romance-you-exo-luhan-humor-baekhyun-chanyeol

I'll look through my other favorite baek stories and add them on :D have fun on your baek binge!

This is a classic so you might have read it: Baby's Breath. If not, then go for it http://www.asianfanfics.com/story/view/378771/baby-s-breath-angst-exo-baekhyun-chanyeol-baekyeol-chanbaek (it's a Baekeol fic but not ). This is the sequel, which is yet to be continued and finished: http://www.asianfanfics.com/story/view/804308/morning-glory-hunhan-sekai-baekyeol-chanbaek

So far I only know about this Baekhyun fic (most fics are and so... yeah. Maybe you're not up to read those).

I also started reading this one: http://www.asianfanfics.com/story/view/730044/not-you-again-arrangedmarriage-comedy-romance-romcom-originalcharacter-exo-baekhyun but the only thing is that the authors stopped updating months ago (don't know why).

And, lastly, this is a chenbaeksoo one-shot collection: http://www.asianfanfics.com/story/view/745121/phobias-----chenbaeksoo-collection-sliceoflife-baekhyun-chen-kyungsoo-baeksoo Baekhyun's ones are in chapter one and five.^^
