Kururu passes on to his platoonmates his new 'life policy' - do something you don't normally do. After seeing Natsumi and Fuyuki react to Kururu's revised behavior with gratitude, the other Keronians take to this new attitude with great zeal - Keroro in particular gets the wrong idea and winds up doing a lot of needless and ultimately annoying things. Even his personal attempt at triggering the Pekopon Invasion goes awry when his congenital ineptitude gets the better of him.
March 14 is White Day, the day that boys who received Valentine's Day chocolates (re. ep 45) get to give something back, and Momoka gets a box of cookies from Fuyuki, which she proceeds to display in her private vault (the cookies that is). However Momoka is looking forward to something more - the perfect date with Fuyuki. Paul enlists the Nishizawa Peach Group's vast resources to create the Super Version Simulator, a virtual reality chamber to determine every possible outcome of Momoka's date with Fuyuki, taking into account every possible situation, down to possible interference from practically every other character in the show... save for one...
某日因為Kururu曹長做了兩件平常不做的事情，而讓夏美與冬樹對他的印象完全改觀，這讓其它Keroro軍團成員進而效訪，Tamama二等兵順利的到了意外的讚美與禮物，但是與Giroro伍長好像就沒那麼幸運了…
收到冬樹送的白色情人節禮物，桃華一心期待冬樹對他做愛的告白．這時波爾護主心切的想要創造出一個完美的告白情境，於是進行了一連串的試驗， 也排除了所有可能的障礙物…終於到了實際演練的這一天，卻碰出了一個意想不到的傢伙
Kururu transmite a sus compañeros de pelotón su nueva "política de vida": haz algo que normalmente no haces. Después de ver a Natsumi y Fuyuki reaccionar con gratitud al comportamiento revisado de Kururu, los otros Keronianos adoptan esta nueva actitud con gran celo: Keroro en particular se equivoca y termina haciendo muchas cosas innecesarias y, en última instancia, molestas. Incluso su intento personal de desencadenar la invasión Pekopon sale mal cuando su ineptitud congénita se apodera de él. El 14 de marzo es el Día Blanco, el día en que los niños que recibieron chocolates del Día de San Valentín (re. Ep 45) pueden devolver algo, y Momoka recibe una caja de galletas de Fuyuki, que procede a mostrar en su bóveda privada (las galletas que es). Sin embargo, Momoka espera algo más: la cita perfecta con Fuyuki.
