A Priest's Secret (priest Wally x y/n)

Priest Wally x y/n but with a twist
I don't know much about this au, but I kinda wanted to add my own spin on it. Your character is an angel in disguise, hearing the voices of those in anguish, you can no longer ignore it. You follow the voices, only to end up in welcome neighbor, a lost cartoon in time. You sense a cover up afoot, but you have to play the part. Will your cover be blown? Or will you figure out the secret the priest is hiding?

Will include intense flirting
NO SMUT (in respects to the creator)
Some swearing but not too much
Twists ;)
