Nikto was a mob boss. After being a former FSB agent, Spetsnaz special forces, tortured, and disfigured, he turned to becoming one of the biggest Mafia bosses in Russia. He still went by his old call sign "Nikto" and wore that hard ballistic mask everywhere. He wore a regular balaclava everywhere else or just to sleep. While at a supermarket he ran into a woman. She had two babies in a stroller and was clearly deciding between formula and frozen food...she was the most captivating woman he'd ever met. He helped her pay for her groceries and left.
He saw her everywhere he went, at the diner she worked as counter staff, she worked at the grocery store he had helped her...a single mom working multiple jobs to provide for her two babies, and a mob boss who was head over heels for her.
