The chapter opens with Momo telling Aoba to hurry so that they can go to the summer festival. Sougo isn't here...because well, he has disappeared for one year without a word to them. Although all the brothers know (Gin&Aoba) that Momo has fallen in love with him, they had never blamed her. Yet she wonders if she hadn't blurted it aloud, whether they would still be living together happily as siblings.
I now know that I'm not related to all my family members. I'm the child from mom's side and Sougo and Gin are children from my dad's side. Although all of us are related to Aoba by blood, I'm not connected to Sougo or Gin. Still, I'm living with Aoba and Gin, for we still want to live together as siblings.
As they walk towards the festival, Aoba comments, "Sougo-niichan even quit the job with that Arisue guy. He could at least tell us what he's doing now."
"Well well now," replies Momo.
Aoba has already graduated from university and is now in a special training school to take over the Suzuki family business. Meanwhile Gin is still taking care of all the family things, although Momo is still unclear as to what his real job is.
Aoba: Do you still want to see him?
Momo: Of course...but...
