Ты know it doesn't really matters who's better. if a Фан chooses GRUVIA или GRAYLU let them be. but if it's my opinion then i еще like graylu even though its impossible :)
P.S.
i also think that hiro made lyon like juvia so that gray will realize his feelings but he might change his mind and continue this Любовь треугольник i mean when i was surfing in the internet i saw something very incredible!!!!!that LYVIA and GRUVIA couple are at SEMI-CANON!!!if it was at semi-canon does that mean that the lyvia Фаны just catch up at the Фаны of gruvia (not so sure) ?! then it also means that if hiro continue this Любовь треугольник then fairy tail might have еще and еще fans!!!!don't Ты agree??!!!BUT THIS IS ONLY MY OPINION THIS IS ONLY WHAT I SAW AT THE INTERNET!!!!if Ты want maybe Ты will go to this web site so that Ты will know what i mean
