Hello Monster

One day, Hyeon receives an anonymous email, which includes a photo of the crime scene in Bangbae-dong, Seoul.

While Hyeon is giving a lecture, Ji An visits him to request an investigation by appealing to his primal nature.

Finally, the perpetrator's face is revealed along with that of his stiff lawyer, Seon Ho.

Ji An becomes expelled from the investigation team after she hands over Seung Hoon to the Chinese public security.

Hyeon now lives at Ji An's house, so Ji An experiences an unusual morning.

During their childhood, Ji An and Hyeon met for the first time. They continue their investigation while hiding their affections to each other.
