And how many chapters ago was it that Haruko kissed Katou on the cheek (once)? All of the other pairings in this series have had far more romantic development than Haruko and Katou (actually, they really haven't had much, if any). Even the Twin Dragons relationship has had a tremendous amount of development compared to Haruko and Katou's. Katou has gone from being Haruko's private bento cook to being Haruko's private bento cook. Of course, that's the whole premise of their relationship to begin with, so it's no real surprise that Haruko doesn't show any romantic interest in Katou. Having an abundant amount of snacks, even, is more important to her than her boyfriend, as demonstrated by her choosing sempai over her boyfriend for the "Love Monopoly" game. It seems clear to me that the big reason Katou doesn't try much of anything to advance their romantic relationship is that he knows that Haruko just isn't interested in him that way. He is her boyfriend in name only. The mangaka is gonna have to be like a magician pulling a rabbit out of an empty hat to convince me that Haruko actually has romantic feelings for Katou. And with only one chapter to go, that's a pretty tall order...
