The heroine Ding Yao is a flight attendant. She has had a strange dream since she was a child. The dream always makes her feel strange and familiar at the same time.
Once Ding Yao was accidentally kidnapped and met Gu Shaoqing. With a mysterious drug background, he has a handsome appearance, is polite, has a dark scholarly atmosphere, but is ruthless and decisive in his actions. It turns out that the kidnapper only kidnapped him because he looked similar to a Japanese woman named Akiko Kuwata, and that Japanese woman had an unknown relationship with Gu Shaoqing.
There seems to be some providence in the dark. From the time the two met to know each other, Ding Yao was gradually attracted to the gentle but ruthless man in front of her. However, the sudden appearance of the missing Sangtian Mingzi, the little girl who appeared frequently in her dreams, and Mingzi's seemingly friendly treatment all made Ding Yao feel a little uneasy in her heart.
After an accident, the truth gradually emerged like duckweed in the water...
