Don't. Finish it or put it on hiatus if you're not feeling it. But I'm sure there are readers who would be sad if you deleted it. Better to just finish it and let it be (or rewrite some day). Who knows, maybe your fic becomes someone's favorite fic in the future?

it will a waste authornim..dont delete it..write till the end and who knows it will get better? :) hwaiting ^^
