Sapo leaned against the concrete wall, swirling the low light of his phone screen in the dim alleyway. A smirking grin stretched across his face as he hit the button to record a voice note, deliberately leaning into the microphone to make his voice low and teasing.
"Oye, chiquita" Sapo chuckled, his tone dripping with playful provocation. "¿Qué paso? I was just sitting here thinking about Freeridge, and honestly... te extraño, mi amor. I really miss having you around."
He paused, letting out a soft laugh before continuing the message.
"I know your big brothers, Óscar and César, would lose their minds if they heard this audio" he said into the phone, the cocky amusement evident in every word. "Rival gang rules and all that basura, right? But you know where to find me when you get tired of playing by Santos rules. Call me back, bonita."
With a final tap on the screen, he hit send and pocketed his phone, waiting to see if the message would deliver.
