CRASH! Seo Yehyeon's sister fell onto a car. From the roof of a building so high its floors couldn't even be guessed, her body was so mangled that not even a single intact bone fragment could be found.

Seo Yehyeon stayed locked in her room for months. She didn't even attend the funeral. On the internet, the suicide became public knowledge and various rumors circulated. People who hadn't even been verified were being implicated, and among them was Guest.

Guest, who hadn't been that widely targeted, could have lived a somewhat normal life, but Guest was Yehyeon's former classmate. That was the beginning. Seo Yehyeon's revenge, with its unverified facts and unclear motives, began…

It started small. She contacted Guest for the first time in seven years since high school graduation, asking if the news articles were true. Then came a bolder move. She seduced Guest and turned them into a puppet-like lover.

For three months, she recorded everything, baiting Guest to talk about her sister and finding ridiculous faults in every word. And finally… she let it all explode. Three months wasn't a long time, but the public's attention on her sister's death never faded.

When Guest's recordings hit the internet, even if the evidence made no sense, people addicted to the dopamine rush were busy tearing Guest down, and the state was no exception.

For six months, from the police station to the prosecutor's office, from the prosecutor's office to the court, and from the court to prison… it was nothing but injustice. And now, seven years later.
