Depressed from her classmates' bullying, Nanako goes to the school's clock tower to spend some time alone.

After Nanako accidentally misses her bus stop, Rei takes her to the park.

Rei refuses to react after hearing Nanako's confession and begins to intentionally avoid her, breaking Nanako's heart.

Nanako and Tomoko decide to go to Takehiko's university fair.

Nanako, Tomoko, and Mariko go the University Fair with Takehiko and Takashi, Fukiko's older brother.

Mariko and Nanako are invited by Fukiko to her country house for the weekend to help her prepare for her birthday party.

Home from the lake house, Fukiko and Rei visit Ms. Asaka's grave on the anniversary of her death, three years ago.

Confused by the events of the party, Rei inquires of Takashi as to why the song upset Fukiko.

Rei reminisces about the first time she met Fukiko, remembering how, even as a child, her pride had still been admirable.

Rei reflects on that double suicide pact that she and Fukiko made shortly after Rei's mother committed suicide.

Mariko's parents are divorcing and she is traumatized, spending the night at Nanako's home to try coping.

At the Student Assembly, Kaoru asks for the abolition of the Sorority.

Two Sorority members, Ogiwara and Komabayashi, persuade Aya's friends, Miyuki and Megumi, to steal and burn the petitions.

The Sorority members are getting scared as the Petition gains movement and their own members begin signing it.

Fukiko continues to pretend that nothing is wrong.

Two weeks after Rei dies, it is the summer holidays.
