Non Senryuu side note: I figured it out, the reason this feels so... Movie like, is the fact that the manga is not on that strip pattern in this volume, it's more structured like a traditional manga. Maybe cause Nanako's not the focus in this one.
Non Senryuu side note: What a hassle it was to create an account here just so I could keep commenting my Senryuus under every chapter. Even if the volume isn't available where I usually read. Anyway, if you do somehow find my comment and you're from Manganato, let me know!
It would be kinda neat :)
