The unnamed protagonist suddenly wakes up in the rain and is picked up by his classmate Karen Inukai. Soaking wet from the rain, Inukai brings the protagonist to her house while he is still confused. While she lovingly dotes on him, she is cold to her own mother. She undresses so she can take a bath with him, embarrassing him as he tries to look away from her naked body. Seeing his own reflection in the mirror, he realizes that he has turned into a dog. Later, Inukai takes him to her room and asks him for a handshake. She then names the protagonist Pochita.
