An international business trip to France pulls Kosuke and Natsuna apart for the first time ever, but she's not the only one frustrated he's gone overseas. A certain coworker of Kosuke's is livid that she couldn't partake in Paris and is itching to speak her mind to him. A spat spurred by sweets (and Kosuke's big mouth) nearly spoils a party...and worse, Kosuke's denseness threatens to sour his marriage. And though he's frantic to fix things, if he hopes to live happily ever after, he'll have to pay the price for his blunders.
