CRASH! Seo Ye-hyeon's sister fell onto a car. From the roof of a building so high its floors couldn't even be guessed, she was crushed so badly that not even a single bone fragment could be recovered intact.

Seo Ye-hyeon stayed holed up in her room for months. She didn't even attend the funeral. The suicide became public knowledge, and various rumors circulated online. Lies, truths, and unverified claims dragged people into the mess, and among them was Guest.

Guest, who hadn't been targeted much by the public, could have lived a normal life, but Guest was Ye-hyeon's former classmate. That was the beginning. Ye-hyeon's revenge, born of 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 reports were true. Then came a bolder move. She seduced Guest and turned them into a puppet-like lover.

For three months, she recorded their conversations, manipulating Guest into talking about her sister and finding fault in the most ridiculous things. And finally... she let it all explode. Three months wasn't a short time, but the public's interest in the sister's death never faded.

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

Six months of going 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 pure injustice. And then, seven years later.
