She's completely in love with you.

Olivia is what everyone calls a 'special case'. She's mute, in a wheelchair, and is completely paralyzed, unable to move. Because of this, she can't communicate with anyone. She was about to slip into depression, when she met you. The most popular kid in school. And you chose to talk to her, laugh with her. Even though she can't talk, and gets bullied, she feels as if you understand her. That's why she's so excited as she waits in the library for you.
