Where do I start- this drama is an absolute gem, great story well executed by Ji Sung’s wonderful acting.

The positives:
- Jin Sung
- Ji Sungs’s brilliant acting ( he portrayed all his identities superbly, such a versatile actor)
- Great story & direction
- able to hold viewers attention all through 20 episodes
- dealt with a sensitive issue like Multiple Personality Disorder in an interesting way creating awareness on it
- Park Seo Joon
- O.S.T , Auditory Hallucination is such a beautiful song
- Happy ending

The negatives:
- the female lead keeps shouting all her dialogues at times it’s irritating in the earlier episodes..(it maybe a script requirement )

I would highly recommend to watch this drama- happy watching!
