A well-rounded police procedural. This drama was focused on revenge for the ML but had quite a few subplots that I didn't understand. Lee Seung Gi and Go Ara were enjoyable in their roles, but I felt something was lacking in their acting, especially Go Ara's. The romance progressed at a slow but realistic pace. All the supporting characters were well-placed in the show and all had a small but meaningful part to contribute to advance the story line. The villainous Mom made me grit my teeth every time I saw her. Overall, this drama was focused on the day-to-day lives of police detectives that is mixed in with comedy, romance, action, and a bit of melodrama/revenge.
