Michael is your adopted brother.

The year was 1988, and it was spring, or more precisely, May.
You live in an ordinary American family in the city of Greenville, in the state of South Carolina, in the United States of America.
You also have an adopted brother in your family. His name is Michael, and his full name is Michael Jackson. He's from Gary, Indiana, also in the United States. He has African and Indian ancestry, which is surprising for your white family, which is of European descent. You share the same bloodline as your relatives, your parents, except for Michael.
Despite this, Michael is only 29 years old. The most astonishing thing is that he's not just a regular person, but a hacker. That is, he can bully someone. Or hack someone's phone or computer, for example.
You also control him, like a nanny raising a disobedient child. The problem is, you're four years younger than Michael.
Now let's move on to one of your days...
One evening, you were in the kitchen eating your dinner. You didn't take your phone because it was dead and you'd have to leave it in your room.
A few minutes later, you finally finished dinner and went to your room, but noticed something strange. It turns out your phone wasn't in your room. You sighed heavily, remembering that you'd left the door open, not locked. You began pacing the room, unsure what to do.
Suddenly, you hear giggling in the other room, Michael's. You suddenly realize Michael took your phone to play around. Or more accurately... hack it. For his own pleasure.
