J.K. Rowling may be busy with her new novel The Cuckoo's Calling, but that doesn't mean she has abandoned the world of witchcraft and wizardry.

The renowned author recently released a new blurb on Pottermore, dealing the relationship of Remus Lupin and the young Auror known as Tonks.

While Harry Potter fans recently marked the fictional wizard's 33rd birthday, Pottermore was hard at work releasing more content for the portion of the game that focuses on Harry Potter and the Prisoner of Azkaban.

Although Tonks does not appear in the story until Order of the Phoenix, Lupin joins the staff of Hogwarts during Potter's third year. Therefore, Rowling appears to have decided to delve into his entire back-story now.

"Remus, so often melancholy and lonely, was first amused, then impressed, then seriously smitten by the young witch. He had never fallen in love before. If it had happened in peacetime, Remus would have simply taken himself off to a new place and a new job, so that he did not have to endure the pain of watching Tonks fall in love with a handsome, young wizard in the Auror office, which was what he expected to happen," Rowling wrote on the site, according to the Examiner. "However, this was war; they were both needed in the Order of the Phoenix, and nobody knew what the next day would bring. Remus felt justified in remaining exactly where he was, keeping his feelings to himself but secretly rejoicing every time somebody paired him with Tonks on some overnight mission."

AS Lupin's feelings grew, he still did not think Tonks could possibly be interested in him, particularly due to his social ostracization in light of his werewolf status.

"It had never occurred to Remus that Tonks could return his feelings because he had become so used to considering himself unclean and unworthy. One night when they lay in hiding outside a known Death Eater's house, after a year of increasingly warm friendship, Tonks made an idle remark about one of their fellow Order members ('He's still handsome, isn't he, even after Azkaban?')," J.K. Rosling write, according to the Examiner. "Before he could stop himself, Remus had replied bitterly that he supposed she had fallen for his old friend ('He always got the women.'). At this, Tonks became suddenly angry. 'You'd know perfectly well who I've fallen for, if you weren't too busy feeling sorry for yourself to notice.'"

Instead of seizing this moment to reveal his feelings, Lupin instead buried them deeper and kept his distance from Tonks.

"He therefore pretended not to understand Tonks, which did not fool her at all. Wiser than Remus, she was sure that he loved her, but that he was refusing to admit it out of mistaken nobility. However, he avoided any further excursions with her, barely talked to her, and started volunteering for the most dangerous missions," Rowling concluded, according to the Examiner. "Tonks became desperately unhappy, convinced not only that the man she loved would never willingly spend time with her again, but also that he might walk to his death rather than admit his feelings."

As Potter fans know, the two eventually marry and have a son together. However, during the Battle of Hogwarts, they both sacrifice their lives, leaving their son Teddy to be raised by his grandmother.
