Who is this about?

Finger tips trace the red lines
The red lines he made on her
Impression was dark
Legs brush against the bruises
The bruises he gave her
Thoughts were compeling
Eyes blink back the tears
The tears he brought her
Poison exploseds through her body
Thumb pushes hair back to see the darkened eyes
The darkened eyes he sold her
Venom pulses through her viens
She doesn't give up though
Together they fight as one.
