By this point of the story it starts to show when some of the girls have had more time to be fleshed out, chapters with karane and nano to name a few feel so much deep than the ones from recent girlfriends that while cute and very enjoyable, still feel anecdotal.
Girls get good fleshing out when you see they don't only show up "their thing" like nano's bit isn't about her being robotic, karane's bit isn't about her being a tsundere, those elements are there but you're showing and telling more stuff about them too.
Another one who got a great moment in that way is kishika, that dommy mommy horny energy... I totally approve.
