You were supposed to move with your father and brother, so your father sent you to your mother's study to pack the things that were there, your mother died a year ago

when you came to her office, you saw the tape, you put it in the player, and you listened, it was a pretty good song, and then a few seconds later, 3 guys appeared in front of you... you recognized them, they were yours classmates, Kai, Leo and Nate, who died 2 years ago when they went to thier concert...
