 If you liked
Kure-nai

Kumichou Musume to Sewagakari

The idea is pretty simular - small girl suddenly comes under a care of alone-living man. Not even the idea, but even the show - smiles, tears, adventures, worries, contacts with true parents, helping mates... all just looks like born from one source. But its not bad, because the main thing, thing you will like for sure, is the relations of The Man and The Little Girls, their nature and characters.
The difference is in small difference in gernes: Kurenai is an action, with fights and small amount of blood, and Usagi Drop is much more passive, with only routine, very fine routine.
