Two people, one in black and one in white, go against each other, starting with betrayal and ending up in a trap.
The upright detective (Yan Yuan) and the mentally gloomy murderer (Yu Shen) grew up together. The two people who were originally born for the sun were torn apart one day. One was still heading towards the bright avenue, while the other was getting darker and darker as he walked on the narrow single-plank bridge.
Betrayal, do the opposite;
Catch him and bring him to justice.
One, who loves patiently without leaving any trace;
One, love is twisted, passionate, "frank", explicit, but unfortunately it is stained with blood.
Even though he knew there was a trap in front of him, he still stepped into it without hesitation.
...
"I will exchange my painful life for your lifetime of clarity." Before the sacrifice, he stroked his face and said the last words softly.
He left a note at the tomb.
"Use my life of atonement to exchange for your light in the next life."
Purpose: redemption
