第 12 集: 潑灑的茶水引發爭執，導致受寒發燒，醫院一通電話更令人困惑。
Spilled tea triggers a silly lover's quarrel. Asami runs out of the house, and eventually Kyosuke follows. Hours pass as the two search the town for each other, even while Asami's father parties with Sakura. He calls the school to apologize the next day, and Iwasaki's suspicions are aroused when she overhears Kyosuke talking to his father-in-law. Having run around in the cold for hours without a coat, Asami succumbs to a high fever the next day. When she collapses in the convenience store, the manager brings her to the hospital and calls the school, telling the teacher who answers that Kyosuke's "little sister" Asami is seriously ill. Iwasaki is not amused to learn that this previously unknown relative has the same name as her rival. (Source: Wikipedia)
