She feels like no one cares about her, every time anyone chooses someone over, especially when her best friend chooses to leave her alone so that her best friend can hang out with other people he doesn't really know.
The girl with the long black hair and the blue ice eyes, always full of pain and suffering, no matter how many people are around her. Only one person can make her feel like she belongs, that one person who completes her, her perfect other half. Without him the girl with the shattered eyes is a just a frozen statue breaking inside, worth nothing more than a passing glance.
She isn't worth anyone's time, she thinks. Invisible feelings. Invisible pain. Invisible girl.
