It seems to me that Luny sorry Lucy (he actually did that) likes Natsu, but he both doesn't notice and doesn't like her back
I'm not up to date on the anime an iv'e never touched the manga though so I might not be accurate
Though about the fateful encounter earlier mentioned in the thread it was actually Wendy that she encountered fatefully.
I used to Nalu and still think it's got a good 65% chance but I still think Nali would make more sense cuz they have more history and he has actually shown signs of affection towards her.
I know this makes me sound like a teenage girl but I still think manga/anime like this (ex. Naruto Bleach Full Metal(not that there is much to be done about) and even Pokemon(I know i just crossed the line bringing pokemon in to this) should add in just a little more romance and almost as important get it to make sense.
I can't be like Oh these 2 people are really popular lets make em a couple!
P.S Nalu all the way!
Course I'm not up to date with Naruto or Bleach so correct me if I'm wrong.
