It is genre bending because the main premise of the story is how a police officer, protects his love interest, Dongbaek, from a serial killer. But really, the story is about Dongbaek (or Camellia in Korean).

Dongbaek is a beautifully written character who is beaten down by life and ostracised as an unmarried mother, but can be fiercely protective. And Kong Hyo-jin wears this ultra-complex character like a glove, with demureness even while she's threatening. There are episodes dedicated to motherhood, particularly one about three single mothers that tugs at your heart. (In fact, there's only one father character in the show and he's shown in poor light.)

Set in a small town, the tight-knit community is inherently heart-warming with a solid supporting cast: Lee Jung-eun (of Parasite fame), Oh Jung-se and Kim Sun-young to name a few.

Among all the stellar performances, Kang Ha-neul shines through. While most Kdramas feature successful and suave male leads, Kang Ha-neul plays an average small-town guy, awkward and simple, and very straightforward, who cries just as easily as he laughs.
