I've been digging through every website and I only found some good ones. Something similar like 'zombie world'. It's really hard to find and I'm already nearing it's end. I don't want to finish it yet (TT)

Have you read any of these? (≧∀≦)
I was so sure that this story's going to break my heart, but I'm glad I wasn't left crying this time. I love them so much they deserve this happy ending more than anyone else
