It's five o'clock in the morning   Conversation got boring   You said you were going to bed soon   So I snuck off to your bedroom      And I thought I'd just wait there   Until I heard you come up the stairs   And I pretended that I was sleeping   And I was hoping you would creep in with me      Put your arm around my shoulder   And it was if the room got colder   And we moved closer in together   And started talking about the weather      You said tomorrow would be fun   And we could watch a place in the sun   I didn't know where this was going   When you kissed me      Are you mine? Are you mine?   'Cause I stay here all the time   Watching telly, drinking wine      Who'd have known? Who'd have known?   When you flash up on my phone   I no longer feel alone, no longer feel alone      I haven't left you for days now   And I'm becoming amazed how   You're quite affectionate in public   In fact your friend said it made her feel sick      And even though it's moving forward   There's just the right amount of awkward   And today you accidentally called me baby      Are you mine? Are you mine?   'Cause I stay here all the time   Watching telly, drinking wine      Who'd have known? Who'd have known?   When you flash up on my phone   I no longer feel alone      Let's just stay, let's just stay   I wanna lie in bed all day   We'll be laughing all the way      You told your friends they all know   We exist and we're taking it slow   Let's just see how it goes   Let's see how it goes      Are you mine? Are you mine?   'Cause I stay here all the time   Watching telly, drinking wine      Who'd have known? Who'd have known?   When you flash up on my phone   I no longer feel alone      Let's just stay, let's just stay   I wanna lie in bed all day   We'll be laughing all the way      You told your friends they all know   We exist but we're taking it slow   Let's just see how it goes   Let's see how it goes
