I have a mistress-like temperament and I like older men. I'm only attracted to men in extramarital relationships. My boss, Department Head Sagawa, is experienced in life, has the composure of a mature man, and is married. I've been interested in him for a while, but when I heard that Department Head Sagawa's wife was pregnant, something inside me snapped. Other people's possessions always seem more appealing. I suddenly found myself desperately wanting Department Head Sagawa.
