Love, Theoretically

Elsie Hannaway leads a double life as a theoretical physicist and a professional fake girlfriend. By day, she pursues her postdoctoral research at MIT, and by night she works for a matchmaking service to support her sister through medical school. Her carefully compartmentalized world crashes when she encounters Jack Smith, a renowned experimental physicist whose work challenges her own theories. Their professional rivalry intensifies as their paths continue to cross in both her academic and secret dating worlds. The story follows their complex dynamic against the backdrop of academia, exploring the collision of theoretical and experimental science alongside matters of the heart. The intersection of reason and emotion plays out through academic debates, workplace politics, and reluctant attraction. At its core, this romance examines how people build theories to make sense of both science and relationships, testing whether logic can truly explain matters of human connection.
