There is a new young man in Blue Water Town and he brings a dog with him. A pastry shop was opened in the most prosperous and lively Rainbow Street. Young people make many kinds of pastries every day, which are loved by the people in the town. The girls all praised the boss for being so handsome.
It just so happened that right across the street from the pastry shop was a piano room. The piano room owner's cat always likes to run to the pastry shop. After running around a lot, the cats and dogs had a lot of fun, and the two owners gradually became familiar with each other because of this and that.
