Megane Apato (Glasses Apartment) by An Tsukumiya
Haruse was requested by her grandfather to be the landlady of the Haruse Apartment or better know as the Glasses Apartment due to the glasses-wearing tenants. I'm not really into the glasses-type even though I wear glasses. But there's more to the story than meets the eye which I find very cute. It looks like a oneshot manga but I'm not really sure.
