She's a mean one--Auntie Takako. She shows up at Nanami's house, says rude things to her, and accuses her of doing stuff with Kyouhei that she hasn't even done (yet)! And on top of that, Auntie Takako's decided to stick around and watch every move Nanami makes...Meanwhile, Kyouhei's getting more and more jealous of her cousin Subaru for no real reason (that Nanami can tell). Which means he's more likely to do something stupid and reveal their true relationship to Auntie Takako! Just how long can they keep up their sibling act before it all falls apart...?!
