I like Chitoge the most too,. Time goes so fast, remember the days when first chapters of manga appeared, did not even imagine it to have so many volumes... Dragged a bit, got annoying too. Atm there are few mangas similar to this one, Nisekoi reminds me of "To-love ru" a bit or "love and lies" , there are more to compare... Plot is different of course, but romance plot is same ...;/
Even after all that's happened, I'm still on the Tsugumi train. Too bad I didn't get to see the type of resolution I wanted with her, but at least they finally revealed to thick headed Claude she's a girl which was one of the funniest scenes in the whole manga imo.
