Zyair was a police investigator who was investigating a serial killer case. He found out a shocking truth that led him to have a knot in his stomach. He was hesitant to tell the truth to anyone.
He found evidence that his own brother was in fact the serial killer. He couldn't cope with the truth, so he asked his trusted colleague about the course of action here. Should he turn his own brother in? Or keep quiet about it. His brother had a wife and two young kids who were staring school soon. He needed to take care of them.
Well, telling his colleague the truth was a mistake because he felt a sense of duty, and he shared the truth with everyone and Zyair had to admit it too because otherwise he would have lost his job. So, he presented the evidence proving that his brother was doing the killings.
This was a difficult situation for everyone involved. And, Zyair's brother went to prison for his crime.
