Another manga you shouldn't miss, basically the story is about a guy chasing a girl, your typical romance manga. But what makes it different is probably how much you can sympathise with the main character. I'm sure a lot of Otaku can relate to his situation and probably go through what he does (except having a bishoujo helping you along the way). Anyway read more for some spoilers.
Ironically man-tearing (T_T)
This is the first time I actually see this kind of thing in mangas(doujin and eroge adaptation not included). It's rare to see these situation, where the main chara feelings is actually stomped upon because of another guy. So this is a really fresh situation even in romance mangas, cause romance is the synonym of harem in an Otaku's dictionary, and for the girl the main chara is chasing to have another feeling for another guy before she is completely rejected or the main chara is completely taken(married) is somewhat a taboo and could be said a repulsive thing to do. If you have any boredom in the usual harem situation you should read this manga to refresh your harem heart.
