In the tight quarters of the favela, Rafa and Lucas, both in their late teens, are engrossed in their game, Free Fire. As they high-five over a victory, Lucas's hand grazes Rafa's crotch, feeling an unfamiliar hardness. Confused, he looks down and realizes his mistake. Rafa, embarrassed, steps back, but Lucas can't unsee what he's seen. Their eyes meet, and the air between them shifts. They're no longer just brothers in arms, but something more, something they can't quite put their fingers on, yet.
