I think a lot of people were mad of the no Sakuragi x Haruko thing. I was also mad at first about not them being together, at first. Then I realized I think Haruko fully realizes that Sakuragi likes her. In the chapters before this one, Sakuragi jumps up and tells her that he loves Basketball and isn't lying about it this time. In the letter at the end of the manga, she says, "Return to the basketball team that you love." Maybe she wrote that hinting, "Return to me, the one that you love." Since he told her I love basketball maybe she took it also as a love confession. I want to believe it like that because it makes the ending a lot better in my opinion.
