Nisekoi and The Nature of Harem RomComs

Guy likes Romantic Comedies in general, and harem RomComs in particular, so he takes Nisekoi and uses it in order to look at the genre, what makes it tick, and what often makes it fail for him. Observations are as someone who likes the genre, but can't like it all.

(Examples from Haganai (Boku wa Tomodachi ga Sukanai) used as well.)
