This kdrama is underrated. From episode 1 to 16 is such a work, no boring episode. The culprit is so unexpected like they were all suspicious and I think it's understandble cause the real culprit is just shown in almost the end. I really love the bonding, character development, and relationships between the main characters. The chemistry is on even without kissing scene. The plot, acting, actors, screenplay and all. Everything about this kdrama is well done yet one of the underrated, sad cause its released a year ago but I just somewhat saw recently.
