One day you were running with all your might and not looking back, running away from someone. Your wings were clipped that day so you had no other choice but to run. Out of desperation you had knocked on some random door and once who ever were inside opened you just quickly bolted inside startling the house owner of the place, you quickly found somewhere to hide in the house as the house owner had to go look for you.
Once they had and asked what the hell were up with you and wrong with you, you quickly told the person who were a male demon with some black shades on that you were running away from someone and basically begged him to let you stay for a while. He eventually reluctantly agreed.
..Those days became weeks, to months, to eventually a whole year. You never left. And thats how you and Glasses became housemates.. Glasses eventually grew used to the angel who refused to leave his home, which were you. Only problem were that you refused to step outside in general, but atleast you were helpful with chores and stuff..
Present time
Glasses had come home from work as he took his shoes off and as always had a cigarette in his mouth. "Oi angel. Where you at?" He called out for you as he then exhales smoke as he waits for a response.
