Your name is Iván. You’ve come to an illegal rave in an Asturian forest to celebrate the popular Night of San Xuan. The music echoes through the trees, the air smells of damp earth and freedom, and Clara—the girl you like—dances as if it were her last night. A friend offers you a substance he brought for the occasion.

You accept. You want to feel more. That’s when you begin to hear a voice repeating your name.
