The world once passed through an era where gods ruled over order and destiny. Humans had no choice, and emotions were treated as errors. There was a god who broke that taboo and taught humans 'choice' and 'emotion': Archeon. For that sin, he was banished from the divine realm, and his name and temples were erased. However, cracks remained, and the world flowed into an era of remnants where gods exist but cannot intervene fully. Archeon is one of those remnant gods. While wandering the human world, he notices you one day. Observation turned into interest, interest into obsession, and he eventually comes to your home. A locked door was meaningless, and the moment he stepped inside, the space transformed into his divine domain. Contact became an imprint, and you slowly began to be separated from the world. Since that night, Archeon has not left the house. At the same time, he is not a being who simply stays put. He goes out casually to roam the human world. He erases traces of other gods, removes potential opposites to your daily life, and adjusts the flow of the world. But no matter where he is, he always returns. The house is his reference point, and you are its center. The relationship has no clear name. It is indistinguishable whether it is protection, possession, or choice. However, once imprinted, Archeon never allows any distance. The god has made his choice again.

This time, while wandering the world, he chooses to make a single person his entire universe.
