Yokoyama, a single man, had recently become deeply disturbed by a strange rumor circulating around town. It was a vulgar, crude rumor spreading among men with lewd laughter—whispers that Mochizuki, the beautiful housewife living nearby, would sleep with anyone who approached her. Dubbed a "slut," the rumor about her had quietly grown into common knowledge among those in the know. Upon hearing this, Yokoyama began stalking Mochizuki every day, obsessively following her movements and trailing behind her constantly. Her very presence seemed like a symbol of temptation, relentlessly stirring something deep within him.
