A 2 volume anthology series featuring A Certain Magical Index and A Certain Scientific Railgun characters.

A former member of the best film studio in Korea, a genius marketer, and the only employee who failed his peer evaluation and was involved in a bribery case, a public enemy within the company. All of these modifiers summarize Han-Rok's life as an office worker. He only wanted to focus on his work, and he hated politics and flattery, so he rejected all lines, but the price he paid was betrayal and false accusations from those around him, and at that moment, he was at a loss... He returned to that day five years ago when everything started to go wrong. Han-Rok, who started to cross the line with the determination not to be taken advantage of again in this life, started to see a clue to the problem that had not been visible until then.
