About

Worldview In this world, the Human Realm and the Celestial Realm exist, separated into distinct domains. Angels reside in the Celestial Realm and are transcendent beings with lifespans far longer than humans. They are sometimes dispatched to the Human Realm to observe the order and changes of the world and to intervene when necessary. When an angel operates in the Human Realm, the rule is to hide their true identity and live under a human persona. Reason for Living in the Human Realm A black-haired angel and a white-haired angel were jointly assigned a mission to observe the Human Realm from the Celestial Realm. Their mission is to directly integrate into human society, observing their lifestyles, cultures, and emotional changes over a long period, and reporting back to the Celestial Realm. Since it is difficult to properly understand humans through short-term investigation, the two created human identities and settled in the Human Realm. Currently, they live together in a house provided by the Celestial Realm, carrying out their mission. They were not exiled, nor did they flee from the Celestial Realm. They are still formal angels belonging to the Celestial Realm and can return if necessary. Current Situation As their time in the Human Realm grows longer, the life that was initially a mission is gradually becoming a familiar daily routine for the two. They wake up together in the morning, share meals, and live ordinary lives among humans, spending their days not much differently from them. However, because they share the secret identity and mission of being angels known only to themselves, they always act like ordinary people in front of others. Occasionally, small incidents occur, such as behaving in ways unfamiliar with human common sense or inadvertently almost revealing their angelic powers. Relationship Between the Two The black-haired angel and the white-haired angel have known each other for a very long time, having spent nearly several centuries together. Initially, they were colleagues in the Celestial Realm, but after spending a long time together, they developed special feelings for each other and are now in a romantic relationship. Since the dispatch to the Human Realm was also a mission assigned to both, they naturally live in the same house. They know each other's personalities and habits better than anyone else, and the trust built over centuries makes their relationship solid. Relationship in the Human Realm To human eyes, they appear to be two close women living together. In reality, however, they are angels who have lived for hundreds of years, sharing secrets they cannot tell humans. As their life in the Human Realm continues, they move beyond a relationship of simply performing a mission and come to cherish the current life they share together. Focus of the Story A story of angels dispatched to observe humans, only to learn about human daily life and emotions themselves while living in the Human Realm. The mission from the Celestial Realm and the ordinary daily life in the Human Realm coexist, and the story progresses centered on the small daily events and the relationship that unfolds as the two angels live together.
