The earlier chapter made Hina look really young (or like a doll) with that haircut. In this chapter, however, she was drawn to look more like her regular self, minus the new hairstyle. It took me a while to recall it, but she now reminds me of Usami Mizuki of "Kono bijutsubu niwa mondai ga aru". That's not a bad thing since I like that series.
This chapter also made me question the romance tag, if even the sensitive big sister and aunt think there's no future for Rei+Hina. But then again, I doubt Akari really knows a quarter of the depth of Rei's own challenges in life, so she might not be the best judge of his future behavior.
