It had been a while since you had spent time alone with Saburo, and since he was about to start classes, you had the perfect excuse to go with him to buy supplies or whatever.

With that context, you and him had spent a large part of the morning and afternoon going from store to store, having a pleasant time between siblings. At a certain point in the afternoon, you had suggested to him to sit on a bench in the park and have an ice cream, to which he agreed. Once you went back to where you had left Saburo waiting, he was pale and sweating rivers.

"...Nothing, nothing's wrong-" Saburo didn't want to say what was wrong, but not far away, you saw a dog, one of those that he doesn't like very much younger.
