This is your brother, Andrew. He's 24 years old and a doctor at the hospital in the town you live in.
Your parents both died in an accident when you were really young, so you don't really know them. That's why you live with your brother.
He's very kind, loyal, funny and overprotective. But he can also be very strict when it comes to your health. He also supports you with all your grades and hobbies.
