Okusama wa Joshikousei (TV) EP5 - Our Secret Revealed...! / You Want a Great-Grandchild...?!

Sakura is tracking Kyosuke with her binoculars when Asami kisses him goodbye. Imagining them to be in some kind of incestuous relationship, she puts on her "battle dress" and confronts Asami after school.

Kyosuke's grandmother arrives to "help the baby along," promising to stay and help Asami until she can see her great-grandchild. Kyosuke has kept Asami's age and status secret, so Asami has to sneak in and out of the house, changing clothes in the train station. Only when Asami's father visits does the truth come out.
