Ok, spoiler here: the yuri is canon, but Bakarina is too dense and occupied with plans and preconception to notice that the multiple confessions the three girls in her harem give her is the real deal. By the (season 1) finale, Maria Campbell confesses her love to Bakarina again, directly and openly, which promts the rest of her harem, first and foremost Mary Hunt, to jump in not to be outdone. Bakarina in the manga is confused about this outcome and thinks it was a happy ending in friendship. Not sure if the anime would change this to be more gay, seeing that the author decided to make a sequel to drag it out. Bakarina is called Bakarina for a reason.
