For Schoolteacher Han Hana, a family curse has ruined all her past relationships: whenever she kisses someone, she turns into a dog every night. Only by kissing the same person again as a dog can she break the curse. So, to avoid any such curse, she has kept her lips chaste her entire life. However, a drunken encounter with her coworker Jin Seon, with whom she has a contentious relationship, turns her world upside down. In her confusion, Hana kisses Seon, causing her curse to surface. As a small and cute white dog, breaking the curse should be as simple as one kiss... but Seon is terrified of dogs?!
