Those last two pages were just awesome, Chitoge's freaking cute with that behaviour and those faces. Especially that last panel, admitting to herself that the onigiri only turned out good because she was thinking of him. But yeah, she has lots to work on. Should have started on something easy and simple, instead of trying to do something fancy (by her standards), that turn out to be disasters. Though the disasters were kind of funny.
But still, yet another filler chapter. That annoys me, although it's good to see Chitoge after all those chapters dedicated to other characters.
