Without a doubt. Genuine development, humour, drama, intensity, emotional and I suppose they do look excellent together. Ice and water are one if you want to think that way:) But overall, because I find them the best romantic sub-plot in FT. Graylu??? Where on Earth did that come from? But that's what shipping is about, you don't have to favour the 'canon' couples and can create whatever you want (Natsu+Juvia for example, which is weird.). But yes, definitely Gray and Juvia, ice and water.

Gruvia because Graylu, just doesn't make sense. Most people ship Graylu because of their looks and Juvia's bizarre imagination. Also in the fairy tail manga
(MAY CONTAIN SPOILERS IN THE NEWEST CHAPTER)










they lived together for 6 months but gray left juvia and betrayed her.
i think they will develop, and become the first popular ship canon. i think Juvia will try to get Gray back and out of the Avatar guild, and idk

i agree im sorry if i offended anyone I just wanted to see the results ^.^ I WAS SO HAPPY WITH CHAPTER 424 BUT THAT PART WITH GRAY
