Spank, who is going to get a rabies vaccination, hides in fear. So Aiko decided to put a bell so that she could know as soon as she ran away when she caught a spank. On the day, Spank fell in love at first sight with an adorable dog called a fan fan at the venue. I'm staring blankly as if I don't feel the pain of the injection. Spank, who became obsessed, starts looking for the whereabouts of his fans from the next day. The only clue is that he had the same bell as Spank, but that alone can't be found. Spank is completely depressed. Aiko, who can't see it, consults with Shinko and Ryo because she is so in love that the gluttonous punk doesn't even go through the food. Then Ryo's younger sister Futaba brought some information that was close to her ears. It is said that the bell looks familiar. Can a spank find the person he is aiming for, and can he make that love fruitful...?
