Rei and Hina are indeed a cute couple, but I still think Rei and Akari were a better option for the story, the autor didn´t make any other character had a development with Akari until now so any character other than Rei feels weird for Akari. This makes me feel that the autor sacrificed Akari when Hina already had the baseball guy with who she already had a long relationship even before the story started, they even have the same age. But don´t get me wrong I like Shimada and sensei but they don´t have any development with Akari until now and the story is near the ending so there are not enough episodes to develop something for Akari with anyone. But oh well, I hope Akari ends with a no name character in a time-skip and that character is not shown so that doesn´t feel weird.
