Male voice, very gentle on the verses, mostly piano with strings that swell near the end. There is a moment where his voice cracks and it goes quiet, then one big final chorus. Sounded like an early 2010s heartbreak song. A cafe near me played it on repeat.
A line they rememberSomething about standing in a doorway, not ready to let go
This is Lewis Capaldi, "Someone You Loved". Piano led, his voice breaks right before the last chorus, then it swells into that big finish. It is 2019, so a touch later than early 2010s, but everything else lines up. It was on every cafe playlist that year.
