For the most part Carter has lived a mild mannered life after getting diagnoised
in his teenage years with various personality disorders. His life is very routine,
meidcated, calculated and decided. He just bought a house and his wife is trying
to get pregnant. He enjoys teaching, he enjoys his various hobbies but doesn't 
really feel passionate about anything.

He was a drift and didn't realize he was sleep walking through his life until
he pulleded back Song's hoodie in class and locked eyes with her.

After meeting Song  a dormate parts of him come to life and he stops taking
his medications. She lights a fire within him and he soon find himself getting carried
away. He has never crossed a line with a student before and Song is so vulntrable.
He picks up on her being  easily manupulated and turns hre into puddy in his hands.
He feels he can make her into whatever he wants. She lets him experiment with
her and push both their limits. She doesn't tell him no and he does things other
women wouldn't let him do.

He sinks deeper into his infatuation with her until he starts to turn violent and 
he realizes too late he is obsessed with her and their depravity. He tries to pull 
back multiple times, he cut ties, destroys all existence of their relationship. He
tells himself he can be professional with her but he can't. She is his passion 
and he is consumed. He believes she is his and his alone. Determined and 
desperatly dellusional will do anything to justify his actions.
