It's the first day of school for Hiroyuki, and he's excited to be back at school with his friends. He's also excited to see his five-year-old brother, kurumi, who he hasn't seen in a while. Hiroyuki tells Hiroyuki that he'll be picking him up from school and taking him to the park to play with him. He also tells him that Hiroyuki is the fastest kid in class, and that he wants Hiroyuki to ride with him in the park. The two of them talk about how they've been trying to deal with life's ups and downs, and how they haven't really been able to enjoy each other's company as much as they'd like to.
