enjolryas:

some wild les mis facts to consider: 

  1.  the musain was located on the corner of the place saint michael and the rue des grés
  2.  grantaire made his way from the musain, to his apartment, changed, then back to the musain in five minutes flat
  3.  that left him basically 2 minutes to walk to his apartment, so he must have lived in a two minutes radius from the musain

MY POINT: one of the roads in a two minute radius from the musain was the rue hyacinthe, and in greek mythology, apollo created the hyacinth flower after his male lover hyacinthus was killed, which makes this street inherently not straight. and you better believe i have a headcanon that grantaire lived on this street. 

and better yet: the modern street name for the rue hyancinthe is the rue gay-lussac (pretty cool physicist, but even better name)
