A fire that spans eleven years, two souls destined to meet.
Eleven years ago, a fire burned down the psychological clinic and Shen Du's life. His best friend died trying to save him, but the arsonist disappeared.
Eleven years later, a series of disappearances brought Shen Du and Lu Heng together. One is a psychological consultant who is so calm that he is almost cold, and the other is a detective captain who is so brutal that he is almost crazy. Everyone said that they were incompatible with each other, but no one saw it - the way Lu Heng looked at Shen Du contained the last ray of light before the flame went out; when Shen Du heard Lu Heng's name, his fingertips would tremble unnoticed.
Because Lu Heng was the son of the arsonist back then.
And when the truth emerged bit by bit, they discovered that the fire was never the end - it was just the beginning of a game of chess. Lu Heng's existence was someone's carefully designed chess piece from the beginning. And Shendu is the real goal.
When the flames ignited again, Lu Heng had to make a choice: go towards the fate arranged by his father, or turn around and embrace the only person he wanted to protect.
"Brother, am I... Dirty too?"
"No, you are my hero. The only light in my life."
