Addicting anime/manga?

i need an addicting anime or manga. Not many series keep me hooked anymore (i got bored w/ bleach, naruto, etc). I have been hooked in the past on fruits basket, and i loved higurashi no naku koro ni, death note, high school of the dead, hikaru no go, bakuman, and that's about it. any manga out there similar to these that i'd like?
