US university student Keely Amelia Cartrett has passed the long days of lockdown by recording dance videos in her living room, many of which have been racking up thousands of views on TikTok.
But none have gotten as much attention as a recent upload which unexpectedly turned into a double act.
The video has racked up over 7.7 million views and show Cartrett performing a dance sequence to 'Imma Be' by the Black Eyed Peas, before noticing she's not alone. As she carries on with her routine, a window washer outside the glass performs a little dance of his own, several storeys up.
"The window man passed the vibe check," Cartrett captioned the video.
Thousands of commenters have expressed their love of the newfound duo and even wondered if it could be the greatest meet-cute of all time.
"Write your number on the window," one person advised.
"That's the beginning of a love story!" wrote another.
The response was so great Cartrett posted a follow-up clip of the pair dancing together again, with the window washer still dangling high in the air.
"He passed the vibe check not once but twice... everyone meet Austin," Cartrett captioned the second clip.
She also addressed the speculated love story in a comment, writing: "You are all invited to the wedding".
Alas, she later said she was still single, much to the dismay of her fans.
As for Austin - we may never know, unless he gets a TikTok account of his own.
