Wang Dahai and Bai Chuan are childhood sweethearts, and both are firefighters by profession.
During a fire-fighting mission, Bai Chuan died, and Wang Dahai was depressed ever since.
And on the day after Wang Dahai's 22nd birthday, a miracle happened!
He's back in 2016!
Wang Dahai returned to 17 years old and met Bai Chuan, who was also 17 years old!
Can he change his future destiny? Is this reality or a dream? Will he come back?
Intention: The love you once ignored can only be understood again when you start over again.
