List of Anime? Please help?

Specifically one with like School Life/Romance with comedy or some other stuff... I dont really care if it has action like High School of the dead but, Give me the name and maybe a short description... *Also if you cann try to make it one with like a highschool guy lives with a girl from the school (blood relationships dont matter) and they fall in love later... Harem would be nice and I dont care how much ecchi there is just no below the waist nudity ;) I know i have a lot of requirrements but if you could find one at least close to this pleaase tell me
