She and Natsu's relationship has gone a long way! He's HELPED her get to Fairy Tail! Personally, Natsu has gone to Lucy's rescue so many times! He's like her PRINCE CHARMING! But, then again, that's NATSU!! SO, NALU（纳兹与露西） FOREVER!!!!!!!
NALU（纳兹与露西） should be the winner because 1.They look cute together 2.Loads of people ship them even Mirajane 3.Just look https://natsuxlucy-fans.deviantart.com/gallery/33719473/NaLu 4.Natsu was the one who brought Lucy to the guild 5.He saved her from the fake Salamander 6.Lucy even saved Natsu and lastly i just think there a good couple XD
NALU（纳兹与露西） for life. For one thing Natsu always goes to save Lucy not Lissana. Also he thought she was dead for what a couple of years? He moved 前锋, 期待 afterward... she was his friend nothing 更多 nothing less. But with Lucy it's like he can't live without her. He goes as far as to risk his life for her. So it's pretty obviuos.
For me I don't really know. I used to be a humungous NaLi shipper and I think in the first few arcs when we found out about Lisanna Natsu and her seemed perfect but after that it just seemed that she wasn't as relevent after she came back from Edolas.; So later on NaLu becomes the stronger ship so i guess i would just say this Nali is cute and all but NALU（纳兹与露西） is 更多 consistant
