It's worth the time. A memorable production is the work of the actors, guided by the director and enhanced by the cameramen, sound engineers and editors, both they and the story. And here, that's what we have. The first episode is a kind of bibimbap, a mixture of fragments, which put me to sleep. Apparently, episode 2 is just as bland... until PARK EUN BIN starts singing. To be honest, I had already given up after the first episode and a half, the time of transmission in Europe contributing to that. After the music appeared on YT, I resumed watching and discovered that what seemed boring at the beginning begins to connect starting with episode 3, scene by scene. In short, the scenario is risky as a format but brilliant in how the crescendo format attracts your interest. After only 6 episodes, although transmitted gradually, 2 episodes per week, it is already in the top 10 worldwide on Netflix, competing with fully released productions. Without being anything ultra-original, it's a good work, for which everyone deserves thanks.
