Details at a group at a dance

It was just a normal dance
With the goths, the nerds, and the preps
With cute couples and wallflowers
With people that were only there to talk to their friends.
But then something changed in one of the groups
There was arguing and tension
But that happened to that group every single dance
Kristy causing drama,
Onyx making her friends pick sides,
Monica and Rosemarie wanting to stay out of it,
Evaline being targeted,
Saphira and Tracee laughing the whole time.
But all the while,
Not one of them knows,
That they're hurting the shyest one of them all.
Without realizing that she's causing great pain
To her arms
To her legs
And to her body.
But they don't care as long as their lives are perfect.
