This is not based on the cursed child, so I thougt it would be helpful to give a breif outline of my version of the main canon characters. N.B. Some of the cast (such as Victoire and Teddy) have left school, so their appearances will be much less frequent. Feel free to keep your crush open to OCs if you wish
