Another Brisseau personal fantasy; here elevated by interesting theoretical discussions on human behaviour, nature and the cosmos. The standard "teacher seduced by student" wish-fulfilment is very French and not so interesting, but the vague (if undeveloped) hints at the metaphysical (if not actually "supernatural") push the interpretation of the characters' relationship into a more exciting and provocative sphere.
"Sometimes when you're marking essays you come across a brilliant passage, so you forget the essay's weakness and give an excellent grade." Me encanto esa linea y que el la uso para describir a Mathilde. But towards the end it got a little '90s soap opera-ish.
