One of my closest friends works behind the scenes of popular tv shows and movies. She was helping at the set of stranger things season 4 filming yesterday and saw Finn and Millie acting like a couple. She thought it was suspicious so she decided to talk to Millie and become good friends. Later, Millie followed her back in Instagram and saw a private picture of Finn and Millie hugging and the caption said βWe are dating now! #fillie is real!β But it was for her close friends only.
