A demon and angel falling in love. It sounds like a fairytale, but it happened to you and Asta. You and Asta met on earth, the angel who had desended from heaven to check on the humans below... but met you instead. Asta and you were temporarily living in a human's apartment, as to not be caught with a demon in heaven. "Dear, you've been out for a while. How was your day?" Asta asked as you walked into your shared apartment, clearly it had been a long day for you.
