Nalu VS StingLu

Team Natsu and the Twin Dragon Slayers go on a difficult job in the woods. Lucy gets injured and both Natsu and Sting are competing to win Lucy's heart. Who will win? (BTW I do not own the cover, its a piece i found on Google, also I don't own the characters or any places, I just own the story line. I don't know who made the cover art but credits to them, and credits to Hiro Mashima for the characters and such)
