I have watched many C-dramas and I am so shocked at how good this show is. This show is highly unpredictable. I spent many nights chatting with others to piece parts of this show together on theories. I can't believe how vested I was in this show.
Because this show was 24 episodes the story line had to get to the point and not drag out stories and the director and screenwriters executed this well. Are there missing pieces? Yes but they told enough to keep the storyline together.

Zhang Ling He - Played Gong Zi Yu very well, you had to see him mature and use his smarts quickly in the show. The costumes looked amazing also. I really enjoyed his character.

Esther YU- Her role was great she played her role very well. I know her objective was to be calm and not show a lot of emotions and I wished she showed more emotions towards Gong zi Yu but that is what makes Yu shu Xin great.

Lu YU Xiao - Playing Shangguan Qian she played the role well, she was veyr cunning and always had a sly look on her face. She understood her assignment. She did a good job.

Ryan Cheng- Gong Shang Jue was amazing he was great , I really enjoyed his character .

Gong zi Shang - I love how Dramatic and silly she is.. Her role is excellent

Jing fan - I was so loyal and I like how the tables turned at the end for him, it was so cute. His storyline was awesome

Tian Jia Rui - Gong Yuan Zhi loved his role also so cool, I really enjoyed his acting

There is more, I just wanted to give major kudos to the cast and I hope there will be a season 2. even if its not the way the show ended was with a bang. the objective was to make us think and provoke thought and I can truly accept that.
