Three high school girls with different perspectives discuss the kinds of secrets you can't tell boys.
Otako explains that girls with big boobs also have big areolae. Galko denies it, thinking she's talking about her.
Seeing Otako with feminine pads, Galko asks if she prefer pads over tampons. Otako answers she should be using tampons, but she’s reluctant to put it in there. While the two agrees wholeheartedly, Ojou appears carrying a tampon.
Galko's skin got really dark as a result of tanning. Otako comments that since Galko's skin has tanned so much, her nipples must be dark as well. Along with Ojou, Otako yells that Galko has dark nipples.
Galko compliments Ojou's pretty hands. Delighted, Ojou compares her hand with Otako's and comments on how small and cute it is. Seeing Galko stare at her own hand, Otako is worried that Galko is concerned about her large hands.
The Class President believes that the size of the boobs and intelligence are inversely proportional, so she thinks Galko is living a very carefree life. But, she changes her mind when she sees the bulletin board Galko was intensely staring at.
Seeing Galko's new lipstick, Otako explains that the lips have always represented the person's genitals. Otako adds that you can also tell the condition of a person's genitals by looking at the shape of their lips, to which Galko inadvertently hides her own lips
Galko, Otako, and Ojou are at the water park. Otako hands Galko a razor believing that her armpit hair is shaggy because she forgot to shave them. Galko angrily says she never lets them get shaggy and shows them her smooth armpits.
Charao, Supoo, and Otao discuss who in their class has the biggest boobs. Seeing Galko’s boobs sitting on the desk, Charao says he has no doubt it’s Galko. However, Supoo comments that Nikuko has large boobs too. Their discussion gets heated...
Otako greets Galko when she enters the classroom, but Galko doesn’t open her mouth and responds by gesture. Galko finally opens her mouth when Otako asks why she’s not talking. She explains that she’s concerned about her double teeth because the main character in the movie was too.
The boys are forced to run during P.E. Once they’re done, it’s the girl’s turn. The boys decide running is awesome when they see Galko running with her boobs swaying around. Then, the teacher instructs them to run again.
Otao is in the nurse’s office due to anemia. Feeling better, he tries to go back to class but decides to take a detour to the deserted hallway. While walking in the quiet hallway, he discovers wet towels on the floor...
It was in April when cherry blossoms bloomed. Most of the cliques in the class have been established. Otako passes papers behind her when she notices Galko sleeping on her desk. Otako’s first impression of Galko was ”she must be a really dumb gyaru...”
