I bet this is the prelude to Yuzuha's h-scene in the game, though I'd like to know if at this point in the game her condition is worsening, and why Eruru isn't "volunteering" for this task.
He bang's them in order of... Eruru, Kamyu, Karura, Touka, Urutoria, Yuzhua.... I think.
kamyu and karura may be switched. Children is actually a central element of the game. Yuzuha wants one say she can contribute and not just be a burden on everyone, and so that Hakuoro won't forget about her. And he's like "Gee, that makes this really awkward as hell." "Oh fine, I love you to." "Okay."
Yuzuha> Yuzuha wants... to have... Hakuro-sama's child.
