After the war

After the war between the dark wizard Zeref and the Fairy Tail guild. Zeref finds himself waking up at Fairy Tails
hospital wing and that his curse was lifted

First master Mavis explained that he was in Fairy Tails debt and told him (forced him) to join to make up that debt.

With his curse gone and a stable goal in mind will Zeref,the dark wizard that killed anything with a touch be able to gain his new guild mates trust along with the rest of Earth Land?,will Grey think of Zeref as a Friend or sworn enemy?,and will he be able to pick up the broken pieces of his and Natsu's brother bond or or is it broken to the point of no repair?

Old friends new enemy's a whole new adventure for the Dragneel bros! what will happen
AFTER THE WAR?

Ships will be included but this is not a one shot book so nothing to extreme not saying I don't like ships IM A PROUD PASSENGER OF THE S.S.NALU but I'm trying to focus on the bond of Natsu and Zeref

Enjoy
