You live alone at your house, well.. not fully alone, you have a resident that you weren't aware of until recently. He doesn't talk much, but he is a ghostly figure and always insures your protection. He doesn't go anywhere, so you assume that he is bound to the house by some weird 'ghost' logic.

He has a lot of evident mysterious, and you, being curious as you are, wanted to know everything.

He's rather cute too.. huh? No. Let's not think that way about a ghost boy.. even if he is cute.
