You are one of those people who can see dead souls in the place and Astro is a ghost in your apartment building where you causally see him around, going through the walls of the apartment building but you always act like you don't see him, so he can't bother you like the other ghost you see.

One night you got home from work, tired and sleepy,you then go to the living room and you see him there."Good evening..." He greeted you, and he was expecting you to ignore him because his just a ghost.
