Such a great game with the audience. Doona's memory scraps heighten the viewer's curiosity to know more. It differs from classic k-dramas as we know them in terms of plot, visualization, and script. Suzy Bae was a surprise to me that she embarked on something more serious, more psychologically demanding. Yang Se-Jong was perfect. The last time I saw him was in 30 but 17, where he was fine, but here he exceeded my expectations. He can be funny, but also incredibly sensitive in serious scenes. That relationship / friendship and funny scenes are pleasantly entertaining, but it is Suzy Bae's character that hides secrets and a story. And it is here that you have to pay attention and watch why she lives the way she does and thus look into her past as a member of a K-pop group. And here we get to secret places that the common human cannot see. Anyone who knows a little about how K-pop groups are formed and trained is not surprised. And the fact that because of her small "misstep," she was actually put to the house where she was hidden and lonely, where no one knew about her, is also not new in the K-pop world. If you don't know anything about K-pop, I recommend that you find something out first so that you know that their life is no joke. And music industry agencies have everything in their hands. Most episodes in the series went slowly but smoothly. Only the last two had a rapid turn, so the viewer has to focus more on the plot because each shot can mean a jump in time. In the finale, we see a pair of ordinary people who have formed a normal couple and live together vs. the central couple, which ended indeterminately... the end is basically up to the viewer... what makes me anxious with such endings... so if there was at least some shot that after x years when her contract ends, what would it be... The series has an atypical 9 episodes. The creators didn't unnecessarily drag out the story, even though I wouldn't be against it. Finally, the best soundtrack songs for me are Daylight from BIG Naughty and Ordinary Day from Suzy. I wish I could see her singing this song live.
