First, Sunako is forced to go on a no-chocolate diet, with predictably unpredictable and disastrous results. Next, Kyohei throws the world off-balance when he lets a little responsibility go to his head. Then frugal Sunako refuses to turn on the air conditioner at the height of summer--and gets a houseful of unrepentant nudists in retaliation. And lastly, Sunako has a little Twilight Zone-ish experience with what appears to be Kyohei when he was just a little boy.
*pffft* This volume is sadly shorter than normal, but the stupid humor is returning to its usual caliber of snorts and guffaws. And Hayakawa even manages to stick in a semi-serious warm-fuzzy chapter, a feat which she seems as surprised and amused by as the reader. :P
