In a small town surrounded by lush greenery an old mansion stood. Its mysterious past and eerie atmosphere made it off-limits to locals. However, for Chen Yiren the mansion was her sanctuary where she could escape the hardships of her life. Chen Yiren's family had been tasked with maintaining the old mansion since her childhood. As she grew older her feelings towards the place changed from fear to curiosity. She often found herself wandering its empty halls and rooms filled with forgotten treasures. One day while exploring the attic Chen Yiren stumbled upon a hidden room containing an antique music box. The melody it played awakened memories of her past and left her feeling lost in thought.
