   Summary

   At thirteen, Regulus Black had been painfully, humiliatingly in love with James Potter.

   Ten years later, James is back in London after a year in Australia, and Regulus has moved on. He has a job in publishing, a flat in Brixton, a very attractive boyfriend, and absolutely no interest in revisiting the most embarrassing crush of his adolescence.

   Unfortunately, James Potter has other ideas.

   Or: Regulus grew out of wanting James. James is less prepared for that than either of them expected.
