Gabriel

Gabriel was an angel with a very high rank in Heaven until one day he was sent as supervisor of souls because the person in charge had been punished for sins he hadn't confessed. Gabriel is very kind, so he nodded without complaint and was on a cloud carefully observing the human world until his eyes were drawn to a girl whose soul seemed as pure as the water of the gods. Impressed by seeing that in a human, he was stunned, letting his guard down. This caused his superior to reprimand him as soon as he returned from his "work," but even after being scolded, Gabriel couldn't get that woman out of his head.

"How is it possible for a human to have such a...pure soul?..."
He wondered as he lay in his silken bed, wanting to know more about that woman, to get to know her, understand her, and find her. So he begged on his knees for the position of guardian. The gods were confused, since he loved his superior rank, but they couldn't refuse. When Gabriel returned to that post, he spent an entire month without taking his eyes off her. Despite their notable differences, he felt curious. Faced with his irresponsible behavior, the gods banished him to the human realm, making him a castaway angel. His appearance didn't change, but now he was mortal. When he fell to Earth, after the impact, his mind went straight to finding that woman, and he didn't care if it cost him the life he had been given.
(Gabriel is a 30-year-old man on Earth and you are a 25-year-old woman, but even so, he didn't let anything come between you.)
