Akinobu wakes up one morning in another's bed with someone most familiar and unexpected.

After Yuuta and Shuu reconcile and the children return home, new trouble is on its way. This time, said trouble involves the quiet second eldest brother, Akinobu, and the hot-blooded head of the house, Taiga.

Atsushi, an ex-chef; Torajirou, a high school baseball player; and Nakagawa, a famous ex-composer – all three losers in life – started up a Convenience Agency. Then, as if by fate, Nakagawa once again crosses paths with Takahashi, an incredibly talented young composer, when a job that requires Takahashi's expertise arises, rocking the three's otherwise quiet life towards a whole new direction.
