Till the Last Petal Falls / Marcus Flint

When the troll met the princess in a Diagon Alley shop.

Marcus Flint was convinced no one would ever want him after spending his years in Hogwarts despite being an Heir to House Flint, he was nothing more than a troll to them.

Dahlia Dursley was kept in eyesight by everyone no matter where she went, she had a beauty to behold, and being the cousin to the famous Harry Potter didn't help the staring.

Marcus wanted to be noticed.
Dahlia wanted to be invisible.
In the end, they saw each other despite everything.

For the sake of the story let's pretend that Vernon Dursley's family originated from France, making the French Ministry of Magic able to track Dahlia's magic.
