Um dude? Do you even watch Fairy Tail? Because that is something out of character for Lisanna to do. I mean,i like Nalu as well,but considering how many they are,i try to look after other fics as well. If you dont like Lisanna with Natsu, either pair her with Rogue or with Gray. Bashing is the worst thing everybody does this days. Be better than that. Hope you listen to my sugestions.

This was really good!

This is great! Im really enjoying this! Keep on writing!

Mira should smack reality into Lisanna. She mistreated Natsu for the entire duration of their relationship; she disrespected him and treated him like some toy. Natsu wasn't happy and realized he didn't love her. What would be the point in being with someone you know doesn't love you, let alone like you. At this point, Natsu hates her.

Lucy shouldn't forfeit her happiness all because of Lisanna's idle threats. Lucy is strong and can certainly hold her own in a fight. I personally believe she is way stronger than Lisanna.

Looking forward to the next chapter :-)
