Any gift will do. After getting it from the manager guy, talk to the reception maid and she should mention that the baron wants to see Ada in a special kind of dress. This won't happen if you already unlocked this H scene in the gallery.

Hmmm, I have used the code previously when I first started playing the game back then, out of curiousity, but I have deleted and redownloaded the game a couple of times since then and recently removed all old saves to ensure that the gallery scenes were locked once again, so is it possible something/a file outside of the game's folder might still be lingering that's causing this? Or is there something I can check on my saves that might reset the state of it?
Alrighty, gonna keep on trying to restart the game until I figure it out; do you have any suggestions as to how I should start it? Like should I start the maid job right off the bat (dress and everything), or before I reach a certain part of the story? Cuz I'm thinking maybe I was a bit too far along for both the story and Ada's lewd level when I started the job. Otherwise, I appreciate you replying and helping me out, thank you!
