Either Millie & Liam or Chloe & Toby for the win.
I think Liam will be faithful. He clearly adores Millie and was saying he will get a job closer to her and is already talking about moving in together.
Kaz & Tyler, no way. Tyler is not that into her. He sounds so self-conscious when he is speaking to her. Nothing is coming straight from the heart. At least he is saying they are not going to rush into anything, (meaning they will split up) rather than trying to pretend she is the love of his life.
Faye & Teddy, just no. She is a nightmare and her obnoxious behaviour should not be rewarded. He is either spineless or prepared to act that way to try to win the game
