Supervalu's Christmas ad features a beautiful twist. Supervalu Ireland / YouTube still

An Irish supermarket's Christmas 2020 commercial will pull on your heartstrings this Christmas season thanks to a touching and unexpected twist. 

SuperValu's 2020 Christmas advertisement centers around a young boy named Conor, who seems worried about whether Santa will be able to come due to that year's COVID-19 restrictions. 

"Is he still coming this year?" the perturbed child asks his mother, who reassures him by saying "of course he is."

The following scene shows Conor writing what appears to be a letter to Santa followed by a scene where he appears to be laying out milk and mince pies on Christmas Eve

Then comes the big twist. It was not Santa Conor was worried about, after all. Instead, it was his grandfather, who arrives on Christmas Eve amid COVID-19 restrictions. 

The pair share an endearing hug in a scene that would bring a tear to a glass eye. 

"Ah Jesus lads, that got me. Christmas was always my grandparent arriving before I went in to see if Santa had arrived. Well played, lovely ad," said TodayFM presenter Declan Pierce. 

"Oh @SuperValuIRL this is amazing so many Irish families will feel this, over Christmas love it," said one Twitter user. 

"Tell me the ad agency I need to run up and smack them for instantly reducing me to tears," said another Twitter user.
