They dated for about three years, lived together for two, argued through almost the entirety of their relationship but their arguments were an intense and passionate extension of the rest of their relationship. They continued to live together even after they broke up for a few months which was all around miserable. There may or may not have been a brief engagement and towards the end they each started seeing other people but coming home to their shared living space, so plenty of opportunity for writing backdated messy scenes. Ideally I’d like to work with the writer who picks this line up to flesh out a lot of their history through scenes and narratives.
