Tsuki no Okinimesu mama

Tsuki no Okinimesu mama summary: In middle school, Ayumu Kamei and Runa Takishima were always at odds.

Now that they are in high school, Ayumu will surely make Runa respect her—or so she thinks. Even now, the charming and witty Runa plays Ayumu like a fiddle. No matter what tricks he plays on her, she falls for them every time, yet even so, she never notices his true intentions. To win, she will have to find his weakness—but Runa's vulnerability is Ayumu herself! Included one-shot: Volume1: Tsuki no Okinimesu mama. (pilot)
