This is not really a recommendation list, but a mere collection of krisyeol stories. And it's been a few months since it's been updated so it's not really complete, but it features lots of - in my opinion - good fanfics and their links.

I really recommend "we are good", A Blessing, Action!, All Night Long, Average, Coffee and Juice, Crash, ea$y money, Floral Leaf, Get on my train, Hooked, Instant Noodles (you should check out all of keychained's krisyeol stories here on AFF, I really think they're worth subscribing), It's not a race, Linked, Persimmons, Pretty People Never Lie, Puzzle Pieces, Speed Dating, The Boy Next Door, Wonderwall, and You are my angel with benefits.

Wow, even though I didn't even mention all of my favourites this list is much longer than expected. x'D

Scrolling through the "krisyeol" tag on LiveJournal might help you, too.
I really liked "25 Bucks on a Starbucks Card" which still isn't listed in the list above.
