This is someone else's theory that i Found, not mine

Lucy finds Natsu and they train together for the next year. Natsu also finds out that he is E.N.D

Gray and Juvia hook up and "get busy," resulting in them having a child, and they also train together.

Wendy will probably join the Council, since she is good friends with Doranbolt.

Laxus will go through training with Makarov, and create a new Fairy Tail guild.

Cana will find her father Gildarts, and she will learn how to use magic better.

And last, but not least, Erza and Jellal will get married. They will make a family.

After 1 year, the Fairy Tail gang comes back to a guild ran by Laxus, and they will prepare for their battle against Zeref and Acnologia.
