Hi there :) I have a fanfiction I am writing with Hanbin as the main. It's not completed and I've taken a break so I can write the rest taking my time with it, but here is the link if you'd like to check it out.

1.This one's good and cute and emotional and a bit angsty. It's very likeable and well written and what's best it's completed so you won't have to wait for every chapter like I did. http://www.asianfanfics.com/story/view/952433/behind-those-lovely-eyes-romance-schoollife-sliceoflife-originalcharacter-slightangst-bobby-ikon

2. I usually don't read stuff that actually have an existing person to be your p.o.v. but this fic was awesome. It's one of my very favorites in this site and I'm so happy I found it. I nearly cried at the end, and that says a lot since I'm not that emotional with stories.

it's not technically a fanfic on AFF but it should be. It's about bobby and an OC with some donghyuk in it. It's called cornfields by ykim on tumblr. So far theres 6 parts i believe and it's the most emotional thing i've ever read. I stayed up untill 4AM binge reading all of the parts. Heres the link to part 1 :) http://ykim.tumblr.com/post/140352992964/corn-fields-pt1-kjw
