12 years

This is a story of the marauders and how they grew up, their years in Hogwarts, and the many years after.
It was the last year for James Fleamont Potter to get Lily Evans to fall in love with him. The number of tries and failures didn't affect him, nothing could stop him from chasing her.
It was the last year for Remus Lupin to be safe in Hogwarts with his friends. The last year where he would have to decide what he will do, and who he will do it with.
It was the last year for Sirius Orion Black to pull off all his famous pranks. But also his last year to finally mature, and maybe find the love of his life.
It was the last year for peter Pettigrew with his friends, for he had no idea what would happen to their group once Hogwarts was in the past.
It was the last year for Lily Evans to avoid Potter as much as possible and continue to deny any affections towards him.
The start of the seventh year, for so many people, but the ending of many was about to come.
1 year left until there is 12.
