In "Kill Me, Heal Me" the son of a powerful rich family has split personalities as the result of a traumatic childhood. He gets help from an intern psychiatrist, but she comes to be more than a secret doctor.

The mystery, and the echoes of the past resonating in the present, work surprisingly well for most of the serial. Yes I felt the characters were rather dumb not to work the mystery out earlier, it could have been more complicated. The beginning is stronger than the end, but most TV serials are like that. There's quite a lot of comedy, and also effective melodramatic scenes. The soundtrack is very good, great at creating moods and enhancing the watching experience. Ji Sung does well to portray the seven personalities, he must have had fun doing this serial.

Fun.
