I feel his dad is trapped somewhere by a mission given by director and the director is working with chairwoman…
I think he was given the same Mission as his son's. I also think Kim shin rok was one of the girl bullies in her younger days who drove the ballet girl towards death and buried her there.
what are the odds that seong's dad is also part of operation? I think he's still alive. do you remember the guy who threw the hammer and ran away it might be him.
