I steal a quick look in Alex’s direction, thinking that actually, I’d be quite happy with someone like him, thank you very much, but give Emma a smile of agreement. ‘You never know.’

Becky fiddles with her phone, changing the music. She’s wrapped some silvery Christmas ribbon around her head like a halo, and starts singing along as Michael Bublé begins crooning from the speaker on the shelf above the sink.

‘Oh God, Becks,’ I groan. ‘Do we have to have Bublé again?’

‘It’s Christmas,’ she says, pulling me up by the waist and waltzing me out of the kitchen door and into the hall. She puts a finger to her lips, shushing me before I can protest. The hall is painted an odd shade, somewhere between violet and grey, and hung with a collection of floral paintings that must’ve belonged to Becky’s grandparents. There’s a huge spiky-leaved plant towering over us in the corner by the stairs. I dodge sideways before Becky waltzes me straight into it.

‘What d’you reckon?’ Her voice is an urgent whisper.

‘They seem nice.’ I try to sound non-committal when what I want to know is why on earth she’d omitted to mention that one of our flatmates was ridiculously gorgeous. ‘How’d you know Emma again?’ I ask.

‘Oh, she’s one of those friend-of-a-friend people. You know, you’re in the same pubs, vaguely know each other through a WhatsApp group, that sort of thing. I can’t remember how we met in the first place. But she was looking for somewhere because the girl she was flat-sharing was moving her boyfriend in, and I had one room left. I’d already sorted you and Alex—’ my stomach does a disobedient sort of swooping thing ‘—and it just seemed like she’d be a nice addition. Everyone’s pretty chilled out, so it should be quite a nice laid-back sort of house.’

‘She seems nice,’ I say, lamely.

‘God, I must pee,’ says Becky, and leaves me standing in the hallway.

I hadn’t noticed, but the carpet looks like someone threw up on a giraffe – it’s yellow and brown with greenish swirls and it clashes so badly with the lilac walls that it must have been the height of fashion at some point in the 1970s. Nobody could choose that colour scheme just randomly, surely?

I head back to the kitchen, realising that I’m feeling a bit fuzzy round the edges. Emma’s kicked off her boots now, and she’s sitting at the table chatting animatedly to Alex, who is sitting opposite. He pushes out the dining chair next to him, beckoning me to join them.

‘Come and get something else to eat.’

He passes me a plate stacked high with tortillas. I think perhaps it’ll soak up some of the alcohol.

‘So how do you know Becky?’ He stretches across the table for the cheese, placing it between me and Emma.

I take a tortilla and spread it with sour cream. ‘I feel like I should make something up that doesn’t make me sound as tragic as this will.’
