Mizuho's sister, Maho, sees what she thinks to be Kei making Mizuho cry so she tries to get rid of Kei. Due to Maho's interference, Kei falls into a standstill upon hearing that Mizuho would be happier without him. Fortunately, Mizuho arrives in time to call him back. Shortly after, mother and daughter say their farewells, but Maho drops by the apartment, pretending to have forgotten something. After kissing Kei on the cheek to make up for her earlier actions, Maho disappears, leaving Mizuho crying over the fact that Kei "kissed" her little sister. Kei tries to explain that Maho kissed him but instead he seizes the opportunity to kiss Mizuho.
