Bug ahoy!
Wierdly, I never seem to get the kissing potion quest for Hermione, but if I chat with her in the library it jumps right into a planned date in the town, citing Harry and Ron being late. Even if the quest chain afterwards is pursued (she's not ready, then she is for a meet in town, and not ready yet again), chatting with Hermione in the library later on offers up the same prior event of potentially spiking her drink with the potion, or just going at it with full on protagonist charm prowess. Pretty sure that's not intentional.
Also, if you tell Ron to slow is roll he claims he'll toss another owl letter to you to try and meet up again, but that doesn't seem to happen, though that's likely just a content issue.
Unless I missed something, still looks like the only ride to the train of poundtown for the female MC is Ron in his overeager state-- I'll, uh, just wait for the librarian with her assortment of tools or Tonks ample, gifted approach of magic, thanks.
Plenty of interesting bits of writing and story here and there to sift through, looking forward to seeing it expand further still.
