Severus survived Nagini's bite and is now on trial before the Wizengamot. Due to a weird loophole in the law books, he has the right to choose any Ministry employee to defend him, and he chooses Auror-trainee, Harry Potter. This SNARRY story is 90% canon compliant, except for the epilogue. If you loathe Severus Snape, don't bother reading this. You won't like it.
