Gyujin is special. He’s the only son of the legendary blue-eyed German shepherd family…and he’s a 26-year-old virgin. To carry on the family lineage, his parents organize an arranged marriage. However, Gyujin cannot think of getting married to a stranger, let alone a female shepherd. He impulsively decides to ruin his parents’ scheming by preemptively announcing that he prefers smaller dogs. In order to cover up his lie, Gyujin asks his childhood friend Youngwoon, a small breed, to act as his boyfriend in front of his parents. Youngwoon agrees under one condition: Gyujin must act like he really has feelings for him! With such a strange demand, could Gyujin be barking up the wrong tree?
