I Thot You Was a Toad's manga / #baby(2)

A series of oneshots in which violence and control are sub-themes: (1) an abused boy finds love in the arms of a kind widower with a baby daughter; (2) a middle manager who cannot smile falls for a new office worker who can't stop smiling; (3) a pair of salarymen negotiate their way through a master/pet relationship; (4) a pair of schoolboys with deceptive appearances negotiate their way through a master/slave relationship.

Butler sub-genre. A young master with a heavy workload has to deal with his sister's baby and an uncooperative, possibly scheming, butler. The extended family dynamics are funny, too.
