There, Nanako goes for a walk near the lake and sees Fukiko playing her violin sadly. That night, Nanako can't sleep and sneaks out and finds Fukiko insane and tormented in a room, reciting Sonnet 18 over and over again. Nanako makes a noise, and Fukiko chases her through the house, but Nanako is not caught. The next day, Nanako questions a maid named Minako about the room - it is Fukiko's old bedroom that has been kept the way it was when she was twelve. Fukiko overhears them talking and fires the maid. Later, Nanako sees Fukiko swimming in the lake, and Fukiko pulls her in. Nanako nearly drowns, but Fukiko comes to her senses and saves her, apologizing that she'd only wanted someone to swim with her. At the end, Nanako re-encounters Minako and she tells her not to worry.
