About
The culprit of a 10-year cold case has finally emerged. It turns out to be the very person who killed Su-hyeon's older brother, framed his younger brother as a criminal, and killed Gong-ryong's friend. Gong-ryong and Su-hyeon are usually not the type to get angry, but for the first time, they are conducting an interrogation together. However, since both Gong-ryong and Su-hyeon have the kind of terrifying personalities where they become eerily calm when truly enraged, they are planning to absolutely wreck(?) the culprit. ^^
