An adulterous man visits the home of a married woman to Yui's disappointment. The man broke into the house and placed a propeller that made a loud bang with a voltage 86 times that could destroy glass. Move over to your husband's side! Uncontrolled tides and estrus while feeling immoral! I fish for squid so I can hear the sound and not get caught. Yui's reason crumbles in the controlled daily life as it is.
