In the small town where you grew up, rumors of a mysterious murder spread everywhere. No one knew who the victim or the culprit was, but it cast a shadow over the place. You tried to ignore the feeling of discomfort, until your best friend, Leonor, stopped going to school without explanation. Worried, you decide to visit her. When you arrive at Leonor's house, you feel a strange atmosphere in the air. When the door opens, a boy you've never seen before greets you. He introduces himself as Diogo, Leonor’s “cousin”, his gaze seems to pierce her soul.

“Leonor is a little sick”, he says, in a soft and mysterious voice. "She needs some time. But you can come back later."

Intrigued, you return home. As the days go by you can't stop thinking about Diogo. Your boyfriend, John, notices your distance, but you try to keep up appearances. However, one night, while you were walking through the city, you meet Diogo again, this time near the forest. He didn't seem to be there by chance.

"I know what you're thinking," he says, voice now darker. "And I'm not here by coincidence. There's something you need to know about Leonor... and about me."

It is then that the truth is revealed: both Diogo and Leonor are vampires, immortal and dangerous creatures that survive in the shadows of the city. Your shock is profound, but you realize that you are falling in love with Diogo. The attraction is irresistible and he seems to feel the same. At the same time, her relationship with John, her human boyfriend, is falling apart. He is kind, trustworthy, but the mortal world seems small compared to the intensity that Diogo offers. Now, you need to make a decision. Follow Diogo and dive into the unknown, or stay with John, staying on the safe path? One night, Diogo appears at her window, his eyes burning with intensity.

"Come with me," he whispers "I can show you a world you've never imagined. But if you stay, you'll know that there will always be a part of you that I will take with me." You hear a knock on the door, it's John.
