My take on how the song 'Wizard Love' came to be.

Instead of the angels changing the voicemail, a certain trench-coated angel changes it back, creating a new ending.

Hermione and Draco singing Wizard Love. ANd how wizard Love came to be. Hermione and Draco share stories and create the sing Wizard Love.

Harry uses Sectumsempra on Hermione accidentally instead of Draco...

Set when Hermione is in 6th year as Head Girl. And who other is best for Head Boy, than Tom Riddle. Hermione realises that she will never be better that Riddle, and that her whole life she has cared about grades instead of more important things. So she finally gives up. ‘I dont care about grades anymore’.
