My wife-to-be is from London. She lived in Manchester for three years while she was at uni, between 2015 and 2018, but even that was only for a few months each year - she went home every summer and for Easter. Anyway, remember this for later. She did live in Manchester but she was frequently back in London and her boyfriend at the time was based down south too.
I'm coeliac, so I was (and remain) a frequent diner at Sweet Mandarin, the (mostly) gluten-free Chinese place that's in the Northern Quarter. I used to live basically round the corner from the restaurant as well while I was at uni, so I was in there basically every weekend with my then-girlfriend between 2013 and 2016-ish. We got to know the staff really well and even ended up at one of their weddings because we were in there so often.
Me and that girlfriend broke up early 2017. I met my wife-to-be not long after.
We'd been together for a couple of years when she moved up here permanently in late 2019... just as the pandemic hit. So I never got a chance to take her to Sweet Mandarin before all hell broke loose. When restrictions lifted, it was one of the first places I wanted to take her because she'd never been before. When we got there, however, my partner realised she had been there once before, years ago, with her ex-boyfriend, around 2015/2016.
We've worked out that we were probably both eating at Sweet Mandarin on the same Saturday night, both sat with our ex-partners, obviously with no idea that either of us were in there or that we'd be getting married about a decade later. Hardly a mind-blowing coincidence but considering my partner's born and bred around Wembley and had no reason to go to a gluten-free Chinese, we've always liked that our story probably unexpectedly began way before we thought.
