"God loves the world, how true is this statement..."
High school student Jiang Fan suddenly woke up in a dark, unfamiliar room. His chest was heaving violently and he had a splitting headache. Opening the curtains, a strange red moon hung in the night sky, reflecting the ominous silence of the world. She remembered that she was Jiang Fan, and that it was Jiang Yue, her "own" sister in this world, who brought her here. But in this room, there were no shoes of Jiang Yue on the shoe rack in the entrance, no notes of hers on the refrigerator, and even the family photo only showed "Jiang Fan" alone - there was no trace to prove that Jiang Yue existed.
The separation between memory and reality stabbed her like a needle: the warmth in Jiang Yue's palm was still in her mind, and the words "must live a carefree life" were still clear, but everything in front of her denied her sister's existence. Are her memories real? Why did Jiang Yue bring her here? What secrets are hidden in this world shrouded by the red moon? In a predicament where he can't find his way back and even the target of his "search" is a mystery, Jiang Fan must search for clues in the broken memories to uncover the truth behind his identity, his missing sister and the red moon.
