Dia, the Chika and Yoshiko Whisperer

Ever since Dia moved to Tokyo for her studies, she always, no matter what, came back to Uchiura on the weekends for at least one day, sometimes even two, to spend time with her beloved girlfriends. She'd never missed a weekend. Until last week. Yoshiko and Chika aren't too happy with that, or at least they act unhappy just for the sake of being goofy. Dia knows how to fix that.
