Marco, an appliance dealer who rose from the bottom, returned to his old apartment building and paid out of his own pocket to install air conditioners for every household, as a way of repaying the kindness he had received years ago. However, his neighbor Marina took the lead in filing claims under various pretexts and engaging in moral blackmail. Without arguing, Marco dismantled all the air conditioners overnight and took them away. When the scorching heat arrived, the old building suffered terribly, while the new building across the street remained cool and orderly. After enduring heatstroke, shortages, and failed extortion attempts, the neighbors finally broke down and had no choice but to turn to Marco for help. Marco presented them with a business contract and insisted that things be done according to the rules. In the end, the neighbors paid to have the units reinstalled—except for Anna, the only one who had stayed clear-headed back then, and who received Marco's free, special care.
