PLEASE READ BEFORE WATCHING!!
Alright, this is different for me, I usually do Ron/Hermione. Ok, Harry and Hermione were dating. Harry went to fight Voldemort, and Hermione and Ron stayed behind at Hogwarts. Well, they heard rumors that Harry had died. Grief striken, ron and hermione turned to each other for comfort and they had an "affair". Well turns out harry wasn't dead and he comes back and finds out about what happened. That's where the video begins, the rest you can gather from the lyrics. Except at the end, just in case it's kinda confusing, harry and hermione are in heaven. harry has forgiven hermione and they live together for eternity.
