Nonoko’s daughter Yaya is back in Japan again after two years of studying abroad. With a foreign boyfriend named Drake Richards.

“Is that why she’s finally back to visit? To introduce him to us? I’d best make him feel right at home.”

If only it were that simple.

“Actually… I’m gonna be a mom, Mom! Just thought you should know.”

A new baby on the way? Talk about unexpected…

“Yaya, when you truly love someone, you plan ahead! Whatever happened to good old-fashioned ‘marriage first’? I guess it’s up to me to test if he’s really husband material.”

Grandma-to-be Nonoko soon discovers Drake has been gallivanting around town flirting with girls. And not just once, either!

(I’ll just have to show my daughter who this scoundrel really is…)

Using Drake’s secret against him, Nonoko attempts to blow his cover once and for all, but… what happens next surprises even herself?!
