They all seem to be connected and know each other outside. Marnie and Lewis obviously have conspired to create their "love story" and probably have the agent working on the story outside, the magazine deals, the beach holiday where Marnie will flaunt her incredible body and have the photos of Lewis carrying her just as the tide comes to splash them etc etc. The break up, the stumbling out of nightclubs, Lewis "caught" cheating, the apology, the expressing of undying love, the slamming the critics, the "I love marnie" and the "I love Lewis" charade. Blah blah blah
