Voice (2009)

Both dramas are about finding out the truth about someone's death and helping the family of a deceased to accept the death of the loved ones.

Both dramas are also on forensics and dealing with issues after death. Ishihara Satomi also starred in Voice.

Same storyline but one is the Korean version and the other one is the Japanese version...............................

Both involve forensics and medical students who come to value what they learn from a veteran who wants to teach them the importance of autopsy in determining the truth behind deaths that otherwise would not be revealed.

These two are both about exploring the past of the dead from a medical view as opposed to a detective investigation. The major difference is that VOICE is a story built up by a medical team whereas in Bull Doctor there are two leading roles from different backgrounds. There is no preference for me they are both excellent shows!
