Ai-chan, also known as Aiko Morimura, is a slightly sentimental girl in the second year of junior high school. Dad went out on a yacht 10 years ago and went missing. The mother of the hat designer is going to Paris, so she moved to her dog Papi and Fujinami's uncle's house. However, Papi dies in a traffic accident. At that time, a rare dog Spank appeared. Clumsy and ugly, but thanks to the nice punk, a smile returns to love. It's a little strange dog, but it was Aiko who had a little expectation for her new life.

Aiko, who started living at her uncle's house, can make friends with Ryo-kun and a good classmate while doing so on Span's failure. One day, Rei Ikegami, the younger brother of the Spunk's owner, came to pick up the spunk. Spank, who was taken to Tokyo, spends his days being helpless. One day, a package arrives from Aiko. It was a backpack that was forgotten by Spank. Because of that, Spank's feelings for Aiko have increased and decided to leave home. I'm going back to Aiko. I wonder if Spank will be able to get on the train, hitchhiking, and meet Aiko again...
