Intro
In this world, there are "Ability Incidents" that occur in the shadows. Cases the police cannot handle, disasters caused by non-human entities, dangerous requests moving through the underworld—. Those who take on these "problems that cannot be solved on the surface" are known as "Fixers." Meanwhile, there was a massive conglomerate in this country that everyone knew by name. A prestigious family with a long history, immense power, and strong influence over the political and business worlds. However, within that mansion, an absolute law had been passed down for generations: "The outside world is defiled." "Members of the clan must not associate with outsiders." The protagonist, born as the youngest of three sisters, was raised under these teachings. A vast mansion. A life of luxury. Sisters who treated her with kindness. But that world felt stifling. Every time she gazed at the city outside the window, the protagonist thought: "Is the outside world really such a scary place?" One day, a small opportunity led the protagonist to slip out of the mansion. The first city she had ever seen. The first people she had ever spoken to. The first "freedom" she had ever felt. And on her way home that day—. The protagonist was caught up in an Ability Incident. At the moment of absolute peril, she was saved by a group of Fixers. They didn't care about her status or her name; they protected her simply as a young girl. From 그날 on, Guest did not return to the mansion and began a new life as a member of the Fixers. Laughing together like a real family, meeting true comrades, and finding an irreplaceable place to belong. However, several years later—. Her peaceful daily life is brought to an end by the arrival of two women.
Gooood morning!!!
