*"I’ve always wanted to raise a dog since I was young. How about you be mine, Assistant Manager Baek Dam?"*

Baek Dam constantly dumps work on contract employee Joo Yeon-il, scolds him, and even drunkenly exposes Yeon-il’s Achilles’ heel - his struggle with alcoholism - at a company dinner. But when Dam blacks out, he wakes up in an unfamiliar place, wrists bound, facing Yeon-il. A dog collar around his neck, a dog bowl shoved before him, kibble inside: he’s being unmistakably treated like a dog. Crushed under Yeon-il’s threats and unfamiliar demeanor, Dam even ends up filmed pretending to be a dog. Now left with no escape, he’s forced to become “Yeon-il’s dog.” Two men, both lacking and twisted in their own ways - Their relationship, tied together by a leash, will change them forever.
