Boku's room is an amusement place for the girls who come out! I never dislike, and I don't like it. Why?

The room of Boku became a place where the housewife of the family came out. I don't like it even if I make an etch. What ever happened? The reason is nothing spoken, almost silent, and no reaction at the time of the etch. But when I removed the rubber and etched, I started to feel embarrassed when I made a voice! If you hit it hard again and again and again, it's a lot! It is expressionless though it is expressionless.
