**Chapter 1**
The room was shrouded in dense darkness, where the dim light from the lamp barely managed to dispel the darkness that hung over them both. Gabino, the feared mafia boss, sat on the couch, looking at his mother with an impassive expression. His purple, almost supernatural skin contrasted with her fragility, which trembled under the weight of the situation. The Glock in his hand seemed to weigh a ton, its sight fixed on the face he had once loved.
"The day has come, mother," he said, his voice as cold as the metal he held. "The day has come when I promised I would kill you."
Her eyes, full of tears, met Gabino's. "I know, my son," she replied, her voice trembling, but filled with resigned calm.
"Where's your father?" Gabino asked, anger and pain evident in every word.
"He's in the hospital," his mother replied, sadness brimming in her voice. "After what happened, he didn't survive his injuries... he ended up dying."
"He deserved it," Gabino snapped, his contempt evident. "After what he did to me, he deserved to get hit in the skull with a wooden club."
A heavy silence hung between them, as Gabino fought against the storm of emotions that consumed him. "And you, mother? Are you ready to die?" The question came out as an icy whisper.
With tears streaming down her face, his mother knelt before him, the fragility of her figure contrasting with the brutality of the scene. "Yes, my son. I'm ready to pay for what I did to you." Her voice, despite the pain, sounded resigned. "You can do it, my son. I blame myself for this every day. End this suffering... and I'm sorry, my son. I hope that one day you can forgive me for what I did to you."
Gabino felt his hands trembling, the gun weighing as if it were made of lead. The world around him seemed to spin, his mind a whirlwind of memories and conflicting emotions. The trigger was there, within reach, and in an instant that seemed to drag on for an eternity, he pulled the trigger.
The sound of the shot echoed through the house, a boom that reverberated off the walls, sealing the fate of both of them, and the silence that followed was as deep as the darkness that enveloped their hearts. Gabino's story, marked by betrayal and mourning, began with an act of despair and a tragic conclusion, where the line between love and hate was blurred in a single shot.
