The long-awaited dog Yumi has arrived at the family home. Everyone joyfully welcomed Yumi, but hidden among them were complicated desires. The younger sister lured Yumi with honey, turning her into a "honey-bait dog" for her own use. Meanwhile, the son began treating Yumi as an object for his sexual desires. When the father discovered this, he flew into a rage, tied Yumi up, and punished her harshly with a vibrator and electric massager. The household descended into chaos, leading them to decide on getting a male dog. Yumi then began a new relationship with the male dog, forming a close bond with him.
