I think this manga will be over before the end of the year, (maybe even by Summer) we've already had Marika's arc done, we've had the MC realise he likes both girls, Haru's arc is now over, we have maybe the arc with Tsugami and deal with her feelings for Ichijou, and the end, well hopefully Ruri and Shu get a arc to deal with their disfuntional relationship...which best Ichijou's relationship with Chitoge and Kosaki by a mile.
The Mangaka stretched it as far as he could with hijinks, the thing is I can't even blame him, he probably never planned for the manga to be this long, but it took off so was ordered to extend the manga further so he filled it with fillers and now it's coming to an end he's tying up loose ends and concentrating on the end, more than we can say for other manga's that crap all over everything and expect us to smile.
