On September 6, 2022 a woman was horribly murdered at her home…her name was Joana Krish and she was 54 years old…she was a research scientist with a PhD in molecular biology at the Nepelle Foundation’s Institute of Biotechnology in Vega City….The neighbors at the crime scene heard three gunshots and when the police arrived there, they arrested the victim’s 17 year old son named Doyle Krish….he was found holding a gun with evidence of gunpowder in his hands…he even admitted that he used the gun…but not on his mom….he stated that there was an intruder but it was not human…it was a monster which Doyle tried to shoot…but the police found no sign of intruding at the place and even found traces of sedative ingredients in Doyle’s drug test even though Doyle strongly denied taking any drugs….moreover, the autopsy doctor for the victim suddenly went missing…the trial went on for 8 months and in the end Doyle was convicted on the basis of a tragedy conflict between mother and son…the court sentenced the defendant to 35 years for first-class murder….however, the media’s attention wasn’t as focused on Doyle as at the academy for the terrible loss of an acclaimed scientist and soon the incident with unsolved mystery was forgotten.

A few years later, the detective assistant Ethan, who has been chasing the truth of that murder case, encounters Doyle through anonymous reports and finds out that the heart of his dead lover Eve has been implanted into Doyle !

Ethan and Doyle feel that something unusual behind the murder is hidden while they start to grow concerned about each other….Together while trying to uncover the facts, they learn the shocking truth of Vega City….What is the identity of the monster that killed Doyle's mother? Is it a coincidence that Doyle received Ethan’s lover’s heart?
