Please don't add a couple that has been in a relationship. That's in the next category. For example: Bella and Voldy did hook up according to the cursed child, so they fall in the next category.
Anyways: Harry./Hermione is my HP OTP>33 (But sometimes I think I like Jilly better)

*is probably gonna get shit for this* but whatever.

Adore <3333333333

I love this couple.

Dramione, Drarry, Snape/Lily, Remus/Sirius <333

I'm not sure if Snape/Lily fits in this category. It did exist as a canon one-sided relationship, so it isn't really fanon. But then there aren't any other one-sided relationships that I can think of. Maybe it could be put with non-endgame canon pairings?
