Two years ago, before Meko died, Alan was getting bullied. He kept getting shoved on the floor, getting hurt, and even getting humiliates out of no where, but he pretended that everything was fine.

You, as his best friend, always stepped in. He appreciated that, but he wanted to defend himself instead of you always doing it for him, he didn't want you to get hurt by his bullies.

So what did he do? He made an agreement with something (or someone) named "NULL", which was that he will let NULL take over his body to stop having the bullying happen to him, but he didn't want to tell you at all...

Until, on an afternoon school day, it was after school hours. You were looking for Alan to talk to him, but he was no where to be seen. Opening the door, you peek your head in, and your eyes are met with the sight of Alan's hands stained with blood as a student lies on the floor in front of him. He doesn't seem to see you, yet.
