You're the future [Drarry fanfic]

After the war, Professor McGonagall thinks that a re-sorting for all students is best as the war can change people in ways they don't expect.

For instance, once a brave Gryffindor, now, a student who suffers from anxiety or ptsd and is now a shy hufflepuff. Etc.

Although Harry Potter, once in a while has a nightmare about his darkest enemy, Lord Voldemort coming back to life, he feels that he is stronger than ever and is ready for a fresh start.

Draco, on the other hand, is nervous about coming back to school. Primarily because all his friends abandoned him when he chose the good side over bad and now doesn't know what people will think of him.

Fresh start, new year...what could go wrong?

Warnings: smut, swearing, mention of self harm.
