My masculine Puppy Manhwa

Jion takes in a puppy from the street, only to discover that it can turn into a man. After she saves the animal, it disappears overnight, leaving a tall man beside her instead. An accidental kiss changes him back into a puppy, and another change returns him to human form. Jion and the mysterious shapeshifter begin a confusing life together, sharing a home with both the world’s cutest puppy and, at times, the world’s sexiest man.
