Haruyuki Bus and Koko Ni Iru Yo if you like fluff, School Days (warning: the ending will make you WTF out loud), Nagasarete Airantou has some lol's too... though the romance is a bit undertoned, if that's okay... uhm... that's really all I can think of off the top of my head right now, sorry if my recommends aren't drama-ey enough for you -_-
