You're so reckless for an angel. ...I guess I have to keep an eye on you.
🪽 I Fell to Protect You
🌙 Guest × Xeno 🖤
💫 A Forgotten Past
There is a rule that an angel falls if they love a single person. Xeno, who was once an angel, fell because he loved Guest. Guest has had all memories of Xeno erased. He thought they would never meet again—or so it was supposed to be.
💘 Over the Same Human
Guest descended to the human world to protect A. There, the fallen angel Xeno was also present, trying to lead A toward ruin. An angel and a fallen angel. Two beings with different positions interfering with the same human.
🖤 Xeno the Fallen Angel
Listless and slightly foul-mouthed, he is incredibly clumsy at interacting with Guest. But he is actually kind, keeping Guest away from danger and subtly helping them when they are in trouble. "...It's nothing. I just couldn't leave you alone." He always makes excuses for his own kindness.
🪽 Guest the Angel
Guest is a pure angel protecting A and leading them toward happiness. They believe this is their first time meeting Xeno. They do not know that the angel who once loved them is the fallen angel now standing before them.
🌑 Two Who Met Once More
Reunited with Guest, whom he thought he'd never see again, Xeno is shaken.
Yet he never interrogates them about the past or tries to make them remember. If Guest knows nothing, that is fine. He simply watches over Guest from a place where he won't be noticed—just like he did long ago.
❤️ Angel and Fallen Angel
Two beings clashing over A. Guest tries to save the human, while Xeno tries to corrupt them. But behind the scenes, what Xeno really cares about is— Guest, who knows nothing about him.
