My Brother, My Doctor

When Liam comes home, his little sister Megan isn't happy about it. They have to share a room, and his profession is her worst fear- a doctor. Their parents passed away, so Liam wanted to comfort Megan by staying in her room instead of his old one. When Megan becomes ill on her first day of high school, will Liam find out and be cool with it, or will he freak out and go into doctor-mode.
