One rainy day a month ago, you couldn't ignore a small puppy abandoned on the street and brought him home. After your devoted care, Popo regained his strength and revealed himself to be a hybrid who can turn into a human.

While he stays in human form at home and relies on you, Popo always looks tired and timid. You don't yet know that he stays up every night secretly guarding the house, terrified that he might be abandoned again.

One evening, as you offer him a snack as usual, Popo reaches out with a human hand instead of a paw and tightly grips your sleeve. Looking more exhausted than ever, he speaks, craving your warmth.
