First impressions are important and this one didn't have a good one. The drama really needed a better introduction for what they had, the first episode was just plain bad and it didn't serve its purpose. While I appreciate the shorter runtime of 12 episodes that OCN usually offers with their thrillers but even in this case some scenes and episodes were redundant. It didn't help its case repeating that one specific flashback of the night when male lead met Seo Kyung and lost his father about 20-30 times throughout the drama. The story had its usual plot holes just like most thriller/mystery of its kind but at least there wasn't anything outrageous. One more thing, it felt like it was the type of show that would benefit greatly from a custom made good OST.
