Lin Xiaoman, a talented illustrator who was ridiculed as a "widow" by the entire Internet, suddenly received a "death blind box" from the deceased - a rusty Walkman three years after his fiancé passed away in a plane crash. When she was wearing headphones and joking about this last "ghost husband's gift" in the live broadcast room, a melodious sound dragged her into the confused rainy night of 2001.
When she woke up, she found that her soul had passed through the body of a "transparent" female high school student who was hospitalized for trying to commit suicide. The person standing guard in front of the hospital bed turned out to be the face that haunted her - 17-year-old Jiang Wan.
In this millennium where there is no WeChat and no positioning, Lin Xiaoman started a "book copy" that changed his destiny. She used her 22-year-old poisonous tongue to attack the innocent boy's heart in 2001, trying to figure out why the boy in front of her looked exactly like her dead lover. However, the closer she gets to the truth, the tighter the Möbius strip of fate becomes.
It turns out that all encounters are reunions after a long absence, and all partings are to cross life and death and run to you again. This is a closed-loop game about "obsession" and "redemption". Only by letting go of obsession can love circulate endlessly in the finale.
