Coming home after midnight on a weekday was the norm. Thursday was in principle a workday. He even worked on three Sundays per month. It was a salvation that he was at least compensated the exact hours of overtime without deception, but he had no free time in his days to spend that money.
Even when he came home, he had not even the energy left to cook himself and his dinner on a weekday was always either a lunchbox from the convenience store or a meal at a restaurant. Now that he was thinking about it, hadn’t it been half a year, since he talked to a woman outside of work or shopping?
