She needed a place to survive. He needed the same flat to sleep. When a crooked landlord double-lets Flat 3B, Lea and Adrian negotiate the only solution that doesn't involve one of them on the pavement: she takes the flat by day, he takes it by night. They'll share a kitchen, a lease, and a fridge - but not much else. The rules are simple. Keep to your own hours. Don't get attached. Leave notes if necessary. The notes were a mistake. Lea is starting over after a relationship that taught her to make herself smaller. Adrian is a paramedic carrying a grief he hasn't named yet, who long ago decided that caring too much was the fastest way to lose everything. Neither of them is looking for anything. Neither of them expected the fridge door to become the most honest conversation either of them had ever had. Flat 3B is a slow-burn, roommates-to-lovers romance about two people who fell in love in the margins - through late-night notes, borrowed mugs, and the terrifying business of letting someone see who you actually are. Perfect for fans of Emily Henry and Josie Silver.
