In this prequel there are 7 parts of the story where 8 actors are the main leads. Every couple of minutes, the story will only focus on one/two leads (with some supporting roles also). Mostly looks like a monologue rather than dialogue between the casts. Compared to the drama, I much prefer the cast in there also Im Siwan, he was born to play Jang Geurae!!!!! I'm quite surprised that there is Moon Seyoon here. Imo his acting in here is the most unstable(?) among the 8 leads in this prequel, I would rather to see his live acting for Comedy Big League (He was a permanent member in 2013).
