Okusama wa Joshikousei (TV) EP10 - Tearful Stargazing / I Won't Lose to a Little Girl

Kyosuke volunteers for night duty at school so that he can watch the stars with Asami, but Iwasaki decides to surprise him with a homemade bento and discovers their inappropriate student-teacher contact.

Iwasaki threatens to reveal Kyosuke unless he agrees to stop "seeing" Asami. The threat actually seems to bring husband and wife closer together, until Sakura's boy inserts himself.
