A very unexpected topic. As most supensful koreans dramas, the director did a godd job as he is very subtle in hints he gives throughout the series.

Unfortunately once the light has been made, plot as well as the performance from Lee Seung-gi tend to go downwards. It is not about the ending but how it was conducted. As well he does a perfect job in the first part and second part of the drama but it wasn’t that investing towards the third act.

Dig up other characters would have been better.
