All these are Sehun/Suho or Chanyeol/Baekhyun with one Xiuchen fic in the midst of it all

And The Rest is Rust and Stardust by luckycharm_mods (I think) on Livejournal 

This is hands down the best Sehun/Suho story out there. It's angsty and fluffy and just too much for my heart to handle argh

The Traits of a Lover by Baekyuu on AFF

This story is painfully heartbreaking and has a TERRIBLE ending but Chanbaek at least got to be together.

When You Tell Me You Love Me, I Really Melt by djjdkim on Ao3

This story was great. Nice and fluffy. I don't read as many Xiuchen fics as I ought to but this one is really great

It's Dangerous Loving You by Kimkai_xoxo on AFF 

It isn't finished yet, but this is a great Sehun/Suho romance. It's genderbent and Sehunah is hot to imagine lmao. It involves Chanbaek & even a Johnten appearance :D

Make You Mine by louw-jones on AFF 

I love mafia Chanbaek. This story is great but wow poor Sehun, always getting shot.
