Ren and Mihato Uesugi have moved to Chiharu in order to find work and a place to live, but it has proven difficult to find employment. Through a series of events the duo finds itself in the prestigious Kuonji house - and subsequently accepts live-in maid positions! Famous Shinra, inventive Miyu and youngest Yume are tough customers to wait on, but with the help of the ex-militant head-butler Colonel, head maid Benisu and other wait staff, Ren and Mihato might just learn what it takes to be the best maid or butler you can be. Their jobs are not easy, though, with everything from inappropriate sibling love to household games to handle!
I'm simply recommending these two because they are both light hearted animes with a story you can more or less care about. They are both harems with there typical anime gags and relatively similar humor. Note: They do have excessive amounts of deviant behavior. If you are into that and want some quick laughs either will do.
