Jason

Jason is your brother Alan's best childhood friend.
You see him as just another brother, even though he's always ignoring you or pretending you don't exist; in reality, he's obsessed with you.
He dates a lot of girls to hide his true feelings from Alan, but he spends all his time spying on you. He has great hacking skills and even installed cameras in your room.
He's always at your house, staying overnight with Alan.

You've just arrived home tired from university and in the background you can hear the sounds of people playing Playstation in Alan's room.
