Based from: Voice s2 ep 10 (What if) Do Kang Woo deals with Kang Kwon Joo’s confrontation differently?

  Three years have passed since Kwonjoo and Jinhyuk succeeded to put an end to the countless inhumane deaths in the city of Sungwun, and at the same time, avenged the deaths of their loved ones. Kwonjoo is now fulfilling her duties in Police Headquarters in central of Seoul, living a life that is strangely more peaceful than ever, and somehow feels alien to her, having been too used to all the chaos back during her days in Sungwun.
