I'm trying a link, if this works, go here, and it didn't work, but anyway, possibly the BEST IchiRuki fanfic in the hole world, (that I've read) go to: http://whinnie10.deviantart.com/art/Sharing-the-Pain-ICHIxRUKI-85917385
That should link you to Sharring The Pain, if not, go to DA and search Ichigo Rukia, fanfic, it's the one that starts out with the words "I'm pathetic... so pathetic" here's the summary!
Rukia is feeling depressed, early that day there had been a thing at school about cutting, Rukia had been interested and tried it ounce on her rist, Ichigo caught her and made her promise not to do it again, but his scars, and they were all for her, now, she has to do it, to repay him, she must scar herself, she's unable to stop, and becomes a person that is too weak to be Rukia, to be his Rukia, had he done something? Was it all his fault? Wat had he done?
Ok, it sounds a little sick, but it isn't! It's REALLY sweet!
