It's both a BL with a dark, crime, mystery and action plot, involving mafia. And also plays partly in a rural area of Thailand.
This series is also somewhat related to investigation on how Ken's friend died and then someone comes to his rescue. Someone who resembles him of a person who he knew from the past. Plus it's a BL series ?
One is BL and the other M/F, but both have a similar vibe and concept - both stories open with one the leads "dying" and the other lead attempting to move on with their lives sort of haunted by their memories. Then a mysterious person who may or may not be the ML who "died" reappears in their lives. Both dramas have a group of villains who want to kill the leads.
