Saving Severus (гет)

It’s only been three years since the battle of Hogwarts and now that life was returning to a sense of normalcy, Hermione felt stuck in the past. She felt like something was missing from her life and she wasn’t happy. So Hermione decides to go on holiday in Greece after divorcing Ronald Weasley.
She is enjoying the recharge of her self and seeing a new place, walking the marketplace. Later she has a few too many drinks and falls asleep in her hotel room.
When she awakens, she’s startled to find out she’s not in Greece anymore. She’s not even in 2001 anymore. She’s looking at Albus Dumbledore from his sitting room couch and the year is 1981.
Now she’s stuck and doesn’t know how she can get back to her time, or how it was even possible. She knows she can’t mess with time, but what if she could save just one person?
