After that, Kasama is introduced. He is this huge guy whom everyone is
afraid of, even though he's actually a nice guy. Nanaka sees right
through that, though. Ahh, how great innocence is.... I don't think
Kasama shows up in later stories, though. It almost seems like a
pointless chapter because of that.
Omiwatari Kei temporarily transfers to Nanaka's school. He's some
popular idol, but it turns out he's not a nice guy at all. Kasama
story and this story are back to back, so it really shows the
contrast. Is the lesson, "you can't tell a guy by the way he looks?"
Anyway, Kei takes an interest in Nanaka. This is, of course, a bad
thing, since he's basically trying to seduce a 6-year old. Well,
regardless of her age, this is a bad thing. This volume ends in a
cliffhanger.
