It will have romance routes for all characters in the first game plus in the 'single' route (the route you beginning without a love interest) there is the option to romance Vesela Brovik or Mathys Aurele (or, again, no one). There is already a secret romance who appears in Bastien's route, whom I won't name here for fear of ruining any surprise. So, adding all that up, there are nine love interests over the eight routes.
