Memories never fade away

What was behind the doors? Which key have I used? A question those two probably asked, but when someone would enter the room, it would be an easy answer. The smell of paper, books, and other scripture were in the air. We went to the middle, Radeus was amazed, Lily looked at everything with a smile and also a kind of happiness that she didn't express as much. She wants to hide it even though she's seen this place several times. The tables and chairs, several books that I picked up earlier. Apparently, whatever you do in such a room will always be saved even if the room is taken away. This is a very convenient way of saving things forever.
