Does Natsu like Erza

no natsu respects her as a fellow guild member, if he likes anyone it would be lucy, though he did used to have a crush on moira and elfman's kid sister Lisanna before she died. hope this helped. :)

p.s. Erza likes Gerard. or at least it appears to be in later episodes that she does. :)

Erza likes Gerard but he feels he can't be with her because he is a criminal and has done her wrong. Natsu might be a rebounder and Natsu not only appreciates Erza's company but He also has shown some emotions for her in Edolas .So it's more than possible.
