Do u think Kim Mu Chan is Kwoj Seok Joo's son.....if not then where is his son, the one that was in Photo Album
I think KMC had a son, the boy in the drawing of Kwon's daughter. because in the drawing they seem to be two children and an adult and that's why KMC and KSJ were so close (?)
And KMC told Ju Min that he also has a story similar to theirs.
The professor created the killing vote to escape from prison and kill Lee Min Soo, the real culprit for his daughter's death.
But now dog mask, your sidekick, is doing things on his own.
JiHoon is the boy in KSJ's daughter's drawing and he knows that the assemblywoman's son is the culprit and that's why he's after him too.
And KMC told Ju Min that he also has a story similar to theirs.
