At twelve o'clock in the morning, Lin Wan, who had been laid off, cheated on, and overwhelmed by gambling debts, was pulled into an infinite game - reincarnation - by a "library card".
In the dungeon, death is real death. She awakened her talent - the Book of Retrospection. Each copy can be retraced once to any point 24 hours ago. The price is: permanently forgetting a memory.
What she didn't know was that "Jhin", who topped the rankings, had been silently guarding her for three years. In exchange for this life-saving book, he sacrificed the memory of his first meeting with her - he remembered to protect someone, but forgot who she was. He thought that amnesia was the end, until he fell in love with her again in the dungeon.
And every time she used backtracking, she forgot about him a little more. Remember the scar on his left eyebrow tonight, forget the hot cocoa he offered tomorrow night. Two people who are both suffering from amnesia, separated by a copy of life and death, are talking about a love that is destined to be erased by their own hands.
"If we forget each other—"
"Then I'll chase you again."
"Did you catch him?"
"Once you catch it, you'll never let it go."
If you forget me, I will chase you again. Even if you forget a thousand times, you will chase it a thousand times.
Intention: Love is eternal
