Permission to Shoot

We have to get the permission from our headmistress for shoot in library. Because we chose to shoot in our school library instead of a public library. So it would be comfortable and safety as my team and I are in school. However, we got permission for shoot there and it didn't take a lot of time either. Another, we have to git permission to Momina's place for shoot the hallway and the room for the character the Siniestra.
