I'm happy that the author is properly spreading the teases across the other girls as well, for a while it was too Chiaki focused. @depzdai Nonoka has said before that she can identify people by their smell, Daisuke especially is very easy to identify.
Other mangakas usually take this kind of opportunity to make shared universe trope with other manga that they wrote, but this one is not. I wonder why it looks like the author persistently avoiding any Ika Musume reference? I wasn't expecting anything but I'm still let down.
