Lin Zhixia, 20 years old, a genius programmer, cold and lonely. Three years ago, her mother disappeared mysteriously, and the police closed the case as "voluntarily leaving home," but she firmly believed that her mother was murdered.
One early morning in the summer of 2024, an old mobile phone appeared out of thin air beside her bed. A person with the ID name "Yanzi" sent a message: "There is someone waiting for you in the future. Don't give up."
"Swallow" knows all her secrets - she peeked at her mother's photos late at night, she used to bite the cap of her pen when writing code, she spilled her coffee today and stained her white T-shirt. What's even weirder is that "Yanzi" sent a photo, taken from her left, and to her left is a wall.
"You won't believe it when I tell you. I'll be yours in a year."
A love that spans lies across time and space, and a race against death to pursue the truth. As the fire day approaches, the two girls go from suspicion to trust, from strangers to love. They have to get the evidence before the flames devour everything, find out the real murderer, and then meet him alive.
