I obviously watched it because of Sho Sakurai. Detective dramas are not my priority or my fave genre but it depends on the plot/acting of the actors. I'm not that impressed in this drama though I do commend Sho Sakurai's acting here. I personally think that he and Keiko doesn't have a great chemistry here. Keiko is perfect for the role of the heiress. I love the music because the theme is from Arashi. I would watch it if I feel like it but not my top priority.
