I just finished watching kill me, heal me. I will rate it 6.5/10. initially its really boring, but after ep 4. The split personalities of Cha started to appear and if I am not wrong he got about 5 personalities, and is due to different causes of the past. There is a plot twist. Watch it if you want to find out. Its a very meaningful show, because many of us nowadays are just putting masks infront of people. and to differnet group of people, its a different mask. This shows shows us that he didnt want it, but because of the situations that he is in, he changes accordingly.. partially to run away from reality.
