I've always dreamed of raising a dog since I was young. You could make that happen for me, our dear Deputy Manager Baek Dam."Baek Dam would shift all his work and all sorts of tasks onto Ju yeon-il a contract employee who he found utterly irritating. He would scold him,push him to the edge and even drunkenly revealed Ju yeon's deeply personal struggle with alcoholism during a company dinner. One day, Baek Dam wakes up in an unfamiliar place, hands bound, and facing Ju yeon . There's a dog collar around his neck, a dog bowl pushed in front of him, and dog food inside the bowl. Clearly, he's being treated like a dog. Overwhelmed by Ju-yeon's different demeanor and his threats, Baek Dam ends up imitating a dog on a video . With this, his fate is sealed, and he is now at the mercy of Ju yeonWhat will happen to Dam, who is now in a position where he will inevitably become 'Yeon-il's dog'? What kind of influence will the relationship between the two men, and connected by a leash have on each other?+
