A mysterious diary from the future suddenly appears on aspiring writer Si Nian's computer. From then on, her reputation takes a complete turn: the "Queen of Bad Endings" rises to become a celebrated author. But a mysterious organization sets its sights on her, drawing her into a future war and leaving her lost in the river of time.
Psychiatrist Jiang Hao falls in love with the author Si Nian he has imagined. He never expects his dream to come true. He stops at nothing to win her love, only to lose her again. He plunges into the river of time after her, crossing ten thousand years just to reunite with Si Nian.
The first time they meet, she walks into his hospital room and says, "Hello, Dr. Jiang. I'm Si Nian. I've always thought there was something wrong with me..."
Before this, she thought she could never love, while he thought he was a pervert.
When they meet again, he asks, "Do you know how many lightning strikes there are in ten thousand years?"
