In the cyber city of 2177, the top hacker "Ghost" was killed during a mission. But his consciousness woke up in the mind of a low-level loser young man. From then on, the loser was forced to start a dual-core life: he was humiliated by his boss during the day and wanted by the whole city at night. Until one day, the beautiful and cold female president of the company cornered him and whispered in his ear: "Stop pretending, 'ghost'... Or should I say, my ex-boyfriend who has been dead for three years?"
