The story is set during when Kai escapes from the Prison World with the Heretics. Y/N, being a close friend of Kai, who had developed feelings for Kai in Prison World - 1994, found out he escaped and was planning to commit mass murder at Alaric and Jo's wedding, decides to confront and stop him. But she gets restrained by Kai instead.
"You're going to regret this," Y/N snarled, jerking against the restraints with all her might. The friction of the ropes would scrape her chafed wrists, but she didn't even give a damn; the fury inside her was burning far more than any literal pain. Kai Parker stood before her, his smile infuriatingly calm, "Regret the time spent with you? Never!" His voice was smooth, almost tender, a stark contrast to the malice in his eyes.
Her heart was pounding in her chest. She had known Kai for months. She had seen his cruelty and moments of vulnerability. But this was different; she'd always been able to keep herself cool around him, but this time, the stakes were up. Too many lives depended on her getting out of there and stopping him.
Their history was a complicated one. Y/N first met Kai in the 1994 Prison World, where she was stuck with Bonnie and Damon. Then, he was the charming sociopath who thrived off chaos and destruction. But in those quiet moments, away from Bonnie and Damon, there had been something else. Kai had a way of making Y/N blush with his relentless flirting and teasing. He had a way of getting under her skin, making her feel things she didn't want to acknowledge.
"Y/N, come on," Kai would say, his eyes twinkling with mischief, "You know you like having me around. Admit it." He'd lean in close, his breath warm against her ear, and she would feel her cheeks flush, despite herself trying to stay stoic.
"You're insufferable," she would throw back, drawing herself up and shooting him a look, but inside, she was thrilled with every fiber of her being when he did that. Faced now with the reality of his actions, those memories felt like a distant dream. The boy who had made her blush was also the man who was capable of unimaginable cruelty.
"You think this is a joke, Kai? You think you can keep playing your twisted games and get away with it?" Her voice shook with her fury, but she made herself meet his eyes steadily.
Kai tilted his head, his smile widening, "Y/N, you don't understand. It's not a game; this is beyond my control. This is destiny. This is what I was put on this earth to do."
"Destiny?" Y/N spat out, eyes blazing, "To hurt people, to cause chaos? That is not destiny, Kai. That is madness."
He took a step closer, his expression darkening, "Madness? Perhaps. But it is madness with a purpose. You see, Y/N, I have spent my whole life being told I was worthless, an abomination. But now, finally, I have power. Finally, I am in control."
Her heart ached for the pain she saw flicker across his eyes. For a moment, she saw the boy who had been discarded, who had been made to feel like nothing. But she couldn't allow herself to pity him. Not now.
"Kai, listen to me," she said, her voice softer but no less urgent, "You don't have to do this. You can choose a different path. You can use your power for good."
He laughed, a harsh, bitter sound, "Good? There's no good left for me, Y/N. Just survival. And the only way I survive now is by winning this fucking game."
Y/N's mind raced for something to say to him, "Kai, if you do this, you'll be alone. Completely and utterly alone. Is that really what you want?"
His smile faltered for just a fraction of a second; then it was back, colder than ever, "Better alone and powerful than surrounded by people who will never understand me."
Y/N felt a surge of desperation. She had to break through to him, had to find a way to make him see reason, "Kai, please. I know you. I know there's still a part of you that cares, a part of you that doesn't want to be the villain."
Kai's eyes narrowed, "It's too late for that, Y/N. It's too late for anything but this." He turned away, and for the first time, Y/N saw a hint of uncertainty in his movements.
"Kai, wait!" she cried, struggling against her restraints, "You don't have to be alone. We can find another way. Together."
He paused, his back to her, and for a moment, Y/N thought she had reached him. Then he shook his head, shoulders stiffened. "I'm sorry, Y/N. But this's the only way I know how to be."
And with that, he walked out of the door, leaving Y/N bound and desperate in the cruel world. Her heart went heavy, knowing she had come so close yet so far from being able to save him. As the door closed behind him, she vowed she would not give up. She would find a way to stop him, to save him, even if it were the last thing she did.
