From Nakama:

A strange household made up of two divorced fathers with a child each. As the children get older, they start to become aware of the strangeness of their own household…?! Following the popular BL about fathers with children, “Kodzure Ookami”, the children become the main characters as we follow their growth, in this long-awaited next volume! Also, a straight-laced tax counselor who is also an idol otaku, and a show pub owner of questionable identity (only half Japanese and also an onee); their fateful meeting and subsequent circumstances. This is the well worth-reading 3rd compilation in the series of this author.
