We meet Essex couple Liam and Leah, who have been dating for five years, and Sami and Rochelle, a teenage couple from Bristol. It was virtual love at first sight for Liam and Leah when they met online. Within a year, Manchester lass Leah had left her family and friends and moved 200 miles to live with Liam and his dad Bill. In Bristol, Sami and Rochelle are living in a very crowded house with three generations under one roof. Having Sami's mum next door isn't great for their sex life and after two years of living with the future in-laws.
