The Dog I Keep Becomes a Billionaire is a 45-episode fantasy romantic comedy, with each episode running about 90 seconds. After a car crash, ruthless billionaire Adrian Shaw and Tessa Reed’s husky swap souls. Adrian wakes up trapped in the dog’s body, while Tessa’s dog controls Adrian’s human body. Only Tessa can hear Adrian’s human voice when he speaks through the husky; everyone else just hears barking. To get his body back, Adrian pays Tessa, then offers her a ten-million-dollar deal to move into Shaw Mansion as his secret interpreter and stand-in at work. As Tessa faces Adrian’s suspicious aunt Vivian, his bewildered fiancée Claire, and corporate meetings with a dog under the table, she and Adrian argue, scheme, and slowly fall for each other. Meanwhile, Adrian’s human body behaves like a dog—fetching balls, hiding meat, guarding food, and competing with Adrian for Tessa’s attention. The series mixes body-swap chaos, office comedy, jealousy, family farce, and sweet romance, building to a finale where Adrian finally confesses properly: he likes Tessa not because she understands him or saved him, but simply because she is herself.
