add important NPCs

when I say important NPCs I mean NPCs with specific roles such as being able to connect with the librarian, or a waiter at the restaurant, although there are already NPCs with roles like the ones you can assign like those who already have those roles teacher, Child Protective Services, there are few roles for the number of places like the cafeteria, the pet store, etc., this could also bring you some benefits, such as if you have a boyfriend or girlfriend, the one who serves you in the cafeteria would stop charging you for the coffee, the one at the pet stores, even in the hospital, a doctor or nurse, could give you discounts or directly be able to have free operations
