This was one of my favourite drama of this year. I just got sucked in. They were able to keep it mysterious till the end. Though I sympathize with Yohan, I was suspicious of him from the beginning till the end. Ga-on'a character was suppose to be the complete oposite of Yohan and while he did seem to agree with Yohan on certain points, being on Yohan's side was conflicting to his self-righteous personality, so he never really commits to him and this part kinda made me mad. As for Sunha, her character was fantastic, she was so evil and way ahead of everyone, even Yohan. Just in the last episode I don't know if the writter was trying to redeem her character and try to make people pity her. It failed on me. I cannot feel sorry for her cause she was evil and manipulative from the beginning, suddenly showing an act of kindness from Yohan as a child moved her heart just fell flat on me. Also the fact that she didn't know what was going on inside the dream home didn't sit well with her character. she was someone who thinks things way ahead of its time, she had all kinda information on everyone but she didn't know what was going on in her own project was just funny. they made her character weak in the finale. they should have let her be the psycho she was and make Yohan decide her ends. This is the only part that disappointed me.
