Aiko tries to tell Shin'ichirÅ her feelings but is interrupted when Miyokichi arrives. While frustrated about Jun approaching Hiromi during school, Shin'ichirÅ asks Noe to stop bothering him for while and ends up getting his belt being pulled out by Noe. Miyokichi later goes shopping with Aiko and the latter stomps out of a shop flustered and tells Miyokichi that she bought the sweater that Shin'ichirÅ had picked up before. Miyokichi gets the hint and feels troubled. Jun goes out with Hiromi on a date Sunday, and after they arrive back at her home, Jun tells her that Shin'ichirÅ and Noe are going out together. Later that night, Shin'ichirÅ overhears Hiromi and his mother's quarrel and has a tussle with his mother and Hiromi. Subsequently, Shin'ichirÅ finds out from Hiromi that he and Hiromi might share the same father.
