There's a war amok in Fiore, and a variety of professional fighters, mages and soldiers from all over the country have been called to defend the empire against the gruelling forces of Lebore.
This of course includes Fairy Tail, prestigiously known for its able wizards, skilled in both defence and offence. Every wizard is eager to lend a helping hand in protection-wielding, including Lucy Heatfilia.
But Natsu Dragneel has other wishes, if things would go his way. In his ideal scenario, the war should probably end without his girlfriend's involvement.
She's an adamant force to reckon with, that blond patriot, so he has to ultimately let her go. He strives to protect her in the battlefield, but amidst the chaos and strife of conflict, what if his eyes stray off of her? What if she gets into intense danger she cannot deal with, attempting to do more than she bargained for? Will they be able to survive through this tough battle unscathed, protected and in each other's eye-view? Or will someone be let down?
Can the love of even this strongest couple survive in the face of bleak darkness and pessimism? Most importantly, can Fiore survive?

Shisui: "Sensei's unique interpretation of the Will of Fire has given the Uchiha Clan a true sense of direction!"
Asuma: "The essence of the jade lies in protecting the people, with the advanced leading the way for the less experienced. Only then can Konoha become stronger!"
Kakashi: "He's my life mentor. He transformed Konoha!"
...
Years later, in the memoirs of Kyoichi, now the Hokage, he wrote:
"I honestly just wanted to be a life mentor!"
