Hen na Ie

Hen na Ie summary:

I, a writer specializing in the occult, received a floor plan of a certain house.
At first glance, it appeared to be an ordinary single-family home, but when I asked an acquaintance, architect Kurihara, for his opinion, he told me, *"There is something strange about this house."*
He began there is something hidden in this floor plan the much-talked-about real estate mystery.
