The plot is about a girl who is killed by a gang. It seems that her boyfriend is also killed, and then it is revenge.

Well, it could be a combination of factors. Maybe there was a history of abuse or a sudden breakdown in family relations that pushed her over the edge.

I don't think so. Such extreme and rare events are often fictional creations or based on highly exaggerated elements.

It's a tragic and complex story. Maybe she had serious mental health issues or was under extreme stress and pressure that drove her to such a horrific act.

Hard to say for sure. It could be a true story, but it could just as easily be made up to shock and intrigue readers. Without more context, it's difficult to determine its origin.

Hard to say for sure. There might be multiple suspects, and the police are working hard to gather evidence and piece together the events leading to the girl's death.

It's hard to say for sure who killed the girl. Maybe it was a jealous rival, or perhaps it was someone with a hidden motive that hasn't been uncovered yet.

Well, often in such real - life cases, there are signs that are overlooked before the tragedy. It could be that she showed signs of aggression or withdrawn behavior in school or among her peers, but no one really paid enough attention.

This situation is unlikely to happen in real life, but it may be described in some novels or fictional stories. In this case, the story would usually tell how the couple was involved in the revenge and tried to solve the problem. The plot may involve various challenges and difficulties that force them to make difficult decisions and face the consequences of their past mistakes.

I'm not sure which specific 'the girl who killed her parents' true story you are referring to. There could be various cases in different regions and situations. Without more specific details, it's difficult to provide a definite account.

Let me recommend you a novel about revenge. The female protagonist's name is also Wan. It's called " Rebirth for a Father ". The female protagonist, Wan 'er, thought that her mother was a docile woman. It was not until her mother changed her father that she began to become irritable. She hated the heavens and the earth and did everything for revenge. Her father was a prime minister, and her mother was killed by a mysterious person. Only later did Wan 'er know the truth. The male lead was called Wan 'er, and she was called Wan' er by her nickname. Moreover, the male lead was a little scumbag, but the female lead was quite good at torturing the male lead. I hope you like this novel.😗
