trying to find this manga!!

does anyone know the name of this one manga where 2 brothers are orphaned bc their parents die, and a couple take them in (i think it's the husband that's related to them).
The wife is super nice and takes care of them and all- it's mostly focused on her relationship with the brothers as a sort of mother figure. I also remember a chapter where she helps out a kid in the younger brothers class bc she's being mistreated by her mother.
