It was me, the fishie one herself.
Because LOVE YOURSELF, PROMOTE YOURSELF, POINT THUMBS AT SELF AND SAY “ThiS GUy!” in a sleeZY VoicE!
Then when you are done telling the world how awesome you are just turn around and skip off into the sunset shouting MOOT MOOT to the universe.
No way, man!
Seriously it can be whateveer you like, Sometimes the theme may specify a pairing but that doesn’t have to be a main pairing and can be left up to interpretation. And i mean i guess it should be related to the theme, but tbh I don’t even know how solid a rule that is too!
name of the game is have fun, meet some new friends and writers and then if you want to you can go nuts in the promo wars.
