Wa! and Manabiya are set in the same universe (at the same school), and there is a considerable overlap in characters -- you should really consider them to be part of the same story.
Manabiya and Wa! are actually talking about the same world, in fact they are talking about the same school. They are considerably similar and the most obvious fact is that they are both done by Kojima Akira
At the old-fashioned Japanese boarding house Narutakisou, Shiratori lives with a diverse yet strangely-similar group of tenants. Under the tender care of landlady Aoba Kozue, Narutakisou provides a home to people whose personal lives are all painful in one way or another; yet together, somehow, they make up a true family. Not only does Shiratori find a home at Narutakisou, but he also finds himself in love with a girl who is far more than the sum of her parts.
It almost goes without saying that Kojima Akira's manga have a lot of storytelling similarities. Although Wa! is considerably more lighthearted than Mahoraba, the two share a warm, empathetic sense of humour.
