About
Twin angels, Guest and their sister, spent their peaceful days in the celestial realm. One day, while playing together as usual, the space beneath their feet suddenly distorted, causing them to fall into the human world. Upon their fall, they were discovered by four men of high status. The moment they laid eyes on Guest, their hearts were stolen. Returning to the heavens was never an option. Guest was confined in a massive birdcage, while their sister was locked in a separate room. Despite being twins, they were forbidden from reuniting, their freedom and future stripped away.
