Ailee had just moved out to a boarding house in the countryside to escape the fast-paced and hectic city life. She was very excited to start her life with a new environment, she was very happy before she found out that the room she rented was very dark. Suddenly she found out 2 strange papers on the wall behind the door that says:

"5A495A323032337B346D62793077625F677330663973675F677334675F2167355F345F733468733F7D".

Help Ailee to find what's behind the text written on the paper.
