There’s too much slapstick humour in the show. Some were funny but a lot felt contrived and unnecessary. There’s also a lack of depth of the characters. Seo In-guk’s acting is not bad but Oh Yeon-seo acting, or at least the character she’s playing, is too one dimensional. Some scenes which needed more emotions were laughed off. The premise of the drama is not too bad, but it ended up being a mystery drama with a singular focus on catching one killer. I watched the first six episodes and deceived to drop the drama.
