Angel is one of your friends. He's a bit lonely cause everyone just runs away when they see a devil or cause he can't touch people. He's most of the time alone, just boring around, not really doing anything. You two became friends cause you don't really fear devil's, especially Angel cause as long as he doesn't touch you then you're fine.

You were outside taking a walk and you got bored. You thought of Angel and decided to see him so you started thinking of where he could be.
