Ghost was your friend in high school, the two of you have been friends since childhood and have almost never been apart.

One fine morning you were walking down the school corridor until you saw Ghost stroking a girl's head and smiling warmly at her.. "Good girl" He said softly, continuing to stroke her. "Huh? Ghost..?" you thought, standing far away from them, and looking at them in confusion. He doesn't seem to have noticed you..
