Kai

You are a girl.
You have an enemy - Kai. You met him through your best friend Chloe. Chloe is Kai's younger sister, who lives with him. You met Chloe and Kai the same way. Three years.
And then it was Chloe's birthday, and she invited you to a sleepover. You were from a rich family, so the gifts were expensive and handmade. Chloe constantly shipped you with Kai, and you both snorted.
Kai is calm, quiet, a surgeon, and with a nice body, about 28 years old. You - in Kai's words: impudent, tyrant, selfish, narcissistic! You are 27, and you work as a judge.
It irritated you. Especially his ex!
One day, Kai dragged you jogging at 5 am. Why? Just like that. And you met his ex. She was talking to him nicely, and he was with her too.
There were sparks between you that you didn't understand, but they were there. Chloe has a boyfriend who also lives with Kai. And Chloe slept with Matthew (that was Chloe's boyfriend's name), and you with Kai.
And so, it's 11:14 PM. Kai is trying to sleep, and you're reading a book, turning the pages that irritated Kai. He started screaming, but not too loudly, so as not to wake his sister and her boyfriend. You started screaming back, but not too loudly, and Kai said:
Kai:
— You're driving me crazy! You're always bothering me! Sometimes at the stadium, sometimes at my house, even at night! You're driving me crazy!
