HPBN-37 White skin floating in the darkness

Ichihiko and his blind sister Ayako lived happily ever after, thanks to the vast wealth left by their father. There was also a blind dog named Jeronimo. Just as Ichihiko got married to Eiko, she disappeared without a trace. Half a year later, Eiko reappeared, accompanied by Dr. Inaba. She had lost her memory; she had no idea about anything that happened in the past. Moreover, her sexual behavior became extremely reckless and bold. Sometimes, she even behaved like a complete stranger, even in front of Ayako. Jeronimo, the blind dog, refused to accept Eiko back and just barked loudly instead.
