If you're interested in reading a plagiarized version of Zibra, find "KWMS An Untold Love Story" by Enchanted-Emotion. The most astonishing part is the last letter Usui wrote. You can compare the date of publication as well. Mine was September the 14th, 2011. The Enchanted-Liar's was January the 14th, 2012.
I am greatly indebted to gamma-rae-star for the tip. (If I have great ideas coming again, I'll dedicate my next fic to you ^^)
