The hidden story of a pet dog who acts like an angel to everyone but turns into a fierce devil the moment his owner appears will be revealed on "TV Animal Farm."

On the upcoming June 28 broadcast of SBS's "TV Animal Farm," the show follows the mismatched love between a dog with legendary looks loved by everyone and his heartbroken owner.

In a cafe that is always bustling with customers, there is a special mascot that catches everyone's eye with his outstanding looks. The star is "Tani," a black Pomeranian boasting a gorgeous appearance. With his doll-like looks and an angelically gentle and sweet personality, Tani monopolizes the love of everyone, young and old, who visits the cafe.

But the moment a certain man steps into the peaceful cafe, Tani's attitude completely flips 180 degrees. He instantly bares his sharp teeth and growls, often throwing the cafe into sudden chaos.

Surprisingly, the person who makes Tani this angry is none other than Tani's dad, Dae-young. While Tani wags his tail and acts completely sweet toward other people, he refuses to let Dae-young—the very person raising him—get close, keeping his guard up with sharp hostility.

It wasn't always like they were worse than strangers. When Dae-young first adopted Tani eight months ago, there were no issues between them, and they actually showed off a warm chemistry. However, as days went by, while Dae-young's love for Tani grew deeper, Tani's heart somehow grew cold.

Dae-young made countless efforts to bridge the distance, but Tani's iron wall only grew stronger. What makes it even more of a mystery is that all the other animals living in the house trust, follow, and act cute around Dae-young. Only Tani expresses an unexplained "aversion" and intense wariness toward Dae-young, leaving the family frustrated as they cannot figure out the reason. Because of Tani's defensive guard that automatically activates whenever his dad appears, Dae-young has been left in a sad state with nowhere to find comfort, both at the cafe and at home.

Where did the love between Tani and his dad go wrong, and will the two be able to return to their affectionate relationship of the past? Their story will be revealed on "TV Animal Farm," airing this Sunday, June 28, at 9:30 AM KST.
