I put off watching this for a while because the plot summary made the concept seem shallow, but it turned out to be the complete opposite. Plot twists on top of plot twists, this drama was really something special. In terms of acting, all of the main leads were fantastic, especially when certain emotions were most difficult to express. As for execution, it's clear that the director was really careful to tie every scene together and not forget the details from beginning to end. Finally, the ending was fleshed out a lot in the final episode despite this series being so short, and left me pretty satisfied with the moral of the story. Highly recommended!
