Episode Title:
Building Nine: For the Love of Pranks.
Episode Description:
Uzuki begins acting strangely over dinner, even switching seats with Yayoi. Haruki catches on and begins to grow paranoid that she has spiked their dinner somehow. After being pressured into taking a bite, he realizes there is nothing wrong with it. After dinner, he finds Uzuki in his room where she asks him to read a book with her. Again growing suspicious, Haruki is put off by her innocent behavior. After she leaves, Satsuki drags him over to show him an anime episode she watched with Uzuki the other day, wherein the younger sister character acts kindly and proclaims her sibling love to her brother, then runs off exclaiming it was a prank. Satsuki believes this is the explanation for Uzuki's unusual behavior, which relieves Haruki that her "prank" is so simple. The next day, Uzuki confirms Satsuki's suspicions while Haruki pretends to be dumbfounded.
