I love Miss Eiki so much. I also like this fanbook although this plot is not like what she would do.
I wondered that if I can stay with Eiki for so many times. I love her purity, her lovable character and the belief of justice even it may be unrealistic. I'd like to tell her it's normal that any boys will have the sexual fantasy to a beautiful, excellent, serious and elegant lady. Will she show a shy face towards me? Haha!
I want to be Miss Eiki's tiny doggie.
