Well it is her fault, she did go through with it very naively but i can also see a bit why she did it, and the relationship that Kirino and Miki have is very confusing for them with the way they both view life.
I do have to agree that the reactions are right on, the way Miki's father reactions is so real its just unbelievable.
I can understand not being very chatty its so good i certianly don't want to spoil it for anyone, but there are definantly times when i could use someone to talk to, befor i start yelling at my TV, though i still might do that after seeing the preview for ep 7, thats going to be wow.
