After installing a new security camera, one woman got an unexpected surprise courtesy of her boyfriend, Chris, and her beloved cat, Biscuit.

In September 2021, Chris agreed to look after his girlfriend's cat while she was hospitalized for a few days.

Chris was aware that the camera had recently been installed, so he kept himself – and Biscuit, of course! – in the frame so she could see them.

Two years later, the woman has decided to share the sweet moment in which Chris picked up Biscuit to make sure she could see him.

Footage of the moment has gone viral on TikTok, earning over a million views since it was posted on Thursday.

In the clip, Chris waves to the cat owner via the camera just as he enters her apartment. Finally, he approaches the lens with Biscuit in his arms and strokes the pet tenderly.

"So glad I could be witness to this father-son bonding moment," the TikToker captioned the video.

In an interview with Newsweek, the owner opened up about the viral moment – and why it proved Chris was the one for her!

The woman's cat and her now-husband are one heart and one soul!

"He absolutely adores my husband, Chris," she said of Biscuit. "Every single day, without fail, he runs to the door, meowing for joy, and immediately flops down on his back, waiting for attention from him when he walks in the door.

"They are completely inseparable."

TikTok users gushed over the relationship in the comments, with one writing, "Soooo...this was when you realized you had to marry him, right?"

Biscuit's owner responded simply, "Correct."

And so, it becomes clear: sometimes even small gestures can lead to life-changing realizations!
