Reiko (Rumi Mochizuki) works as an interior designer. However, her husband lives a lazy life, relying only on Reiko's income... Her only joy is working with a dandy client. He is a gentleman with perfect attention to detail and work ethic. When she is invited to dinner with him, it is his dull young subordinate who turns up... The young man begs her to have sex with him just once, but... this young man is not normal!!
