Ai, well, sure Noe is a good person and so on. Hiromi is pretty much no-go, feels like she is somewhat mentally unstable. Yeah, well, Noe dosnt seem to be normal for my taste either, but for some reasong I feel like Ai would be "good" choise for me.
Ai would be good choice for me.
Noe would be interesting personality too, and I definately would want to know her.
Hiromi doesn`t interest me, well, yay, even if I knew that she were my half-sister, it still wouldnt change anything, it would just clear up a few things, thats all. Hiromi just doesnt seem to be an interesting person, or atleast not for my taste.
