Kintama begins the story as Juicy's boyfriend but breaks up with her, explicitly stating his desire for a "model girlfriend" and that they are "not compatible physically," directly citing her weight. This action triggers Juicy's emotional distress and subsequent depression. He works at the university library with Paprika. When confronted about the breakup, Kintama justifies his decision by explaining that people constantly question why he is with Juicy, suggesting he "could do better." He expresses frustration with societal judgment, stating, "people are always watching me... I got sick of people telling me that, so I decided to get a new girl," and dismisses concerns about Juicy's feelings with "She'll get over it." His presence at a summer barbecue in Wadabori Park ignites an immediate romantic interest in Chibiham.
