She is an ordinary librarian. The only special thing is that she has the same dream repeatedly every night - the white bell tower rings twelve times in the fog. The sound of the bell makes her chest feel tight, but she can't remember anything when she wakes up.
On the day when the end came, all the light in the world went out. Gu Wan was pulled into the infinite space called "Roulette", struggling to survive in each twisted copy. There was something looking at her in the mirror of the abandoned hospital. The wedding in the medieval manor was repeated thirty-seven times. Each number in the city of amnesia corresponded to a sealed past - and in the corner of all copies, there was an identical ancient symbol hidden.
Her awakened "time and space perception" can detect abnormalities in the timeline, but every time she activates it, the bells in her head ring more clearly. Teammates join one by one: Lu Chen, who is taciturn but always appears at critical moments, his spatial ability perfectly complements Gu Wan; medical student Su Qing, programmer Xu Yiming, and racing driver Zhou Ye, the five-person team builds trust in each other on the edge of life and death.
And all the clues ultimately point in the same direction: the core of the roulette wheel. Hidden there is a forgotten name, a blocked memory, and a promise that should have been completed three years ago.
"The way home" is not just a way home, but also to find the person who has been erased from the world.
When Gu Wan finally recovered her memories from when she was fifteen years old, she discovered that the truth about Roulette was far crueler than she imagined. And the man who had been by her side had been bearing a price she didn't know from the first day.
She wants to take more than just herself home.
