Is your interpretation of future Raz and future Lili dating?
Short answer: it’s complicated
Strictly by my interpretation of their educational/social/personal trajectory as kids, they have been long standing coworkers who know each other TOO well. The hotsy totsy part of their relationship is over since they are both looking at the beginning of their 30s. Raz has become so wrapped up in his work that he barely stays in his trailer house, which is a depressing dump of filing and storage (He sleeps at work). Lili is trying to oversee her fathers retirement. She already has the possible position of Grand Head looming in her future and dreads it. Her father let slip he would like to see Raz as grand head one day, which really bothers her to no end because Raz is the most complicated man she knows, keeping his many neurotic tendencies medicated with his meticulous by-the-book organization. If he made grand head, she’d likely get stuck as lesser head, which messes with their dynamic since Lili is normally the reckless renegade while Raz runs behind her putting out fires (both figuratively and literally. They are fire and water)
So the long short of that, they are career competitors. They still have affection for each other but their shared occupation and familiarity don’t make for dating without a hitch.
