High School Lolita - my crushing love story

"Whatever our souls are made of, his and mine are the same."
(Emily Brontë, Wuthering Heights)

Chloé Duchêne had a very hard time in 10th grade: being the target of bullying, she was reduced in a state of helplessness and solitude. Fortunately, at the start of 11th grade, her literature teacher, Matthieu Prevost, notices and takes action to put a full stop to Chloé's harrassment. And it works! Chloé is finally able to live the rest of her highschool years in peace, all thanks to Mister Prevost's intervention.
She is therefore grateful to Mister Prevost and, if the latter tells her he just did his job, Chloé is determined to thank him properly. Doing so leads the teacher and his student to discussions that develop their bond... and eventually make them embrace an unfortunate romance.
But... could it just be true love unaccepted by society? Or is this romance bound to be destructive? And, if so, how will Chloé escape from Matthieu's grasp?
