[K-DRAMA] "Tunnel" parallel stories?

the actors & actresses awesome, well I am curious. a 30 year old murders? hmmm, wonder if it could parallel to the murders in the 90’s (gap dong) (signal) (10) y’know the women that were murdered, think with stockinmgs, tied up etc. would be quite interesting. this drama has me at the edge of my seat. awesome! just too short.

As far as I know, Tunnel, Gap Dong, and Signal were all based on or inspired by a real serial murder case in Korea in the '80s.

There’s also an excellent movie based on the same murders, Memories of Murder (2003).

oh yeah I just finished that movie a week or so. I like dramas & movies like this! now if some could get solved
