The Flatshare (season 1)

Tiffy Moore urgently needs to move out of her ex-boyfriend's house, and preferably to a cheaper apartment. Leon Toomey works nights at a hospice and needs money. And then they find a crazy, yet perfect solution: Leon will live in the apartment during the day and Tiffy will live at night and on weekends. They see only each other's footprints - dirty cups, scattered shoes, scarves and books - and write notes to each other: about who has to take out the trash, put things away, fix the heating. They also share news about a jealous girlfriend, an obsessive ex, friends, and problems at work. How many notes does it take to befriend someone you've never seen? And after how many notes can you fall in love with him?rn
