It would be nice if there's a chapter where Kasumi and Sakurako talk about their relationship, in a serious way. Like, it's fine even if they don't end up labeling their relationship as girlfriends and just continue with the comfortable "as long as we're together forever" kind of relationship. But with all the people around them getting together as girlfriends and those people assuming them as girlfriends already (which is surprisingly not, which make me surprised as well when Sakurako said it), I just hope they will have the "serious talk" soon.
But then again, I really am happy with the light slice of life, everyday pure true love story vibe I get from this manga. So there's that too.
