Young bachelor Horie was deeply disturbed by a mysterious rumor spreading through town. The rumor centered on Yuriko Shio, a beautiful married woman living nearby. No one knew whether it was true or just gossip, but people whispered that she would sleep with anyone who asked—spreading her legs instantly, as if deliberately hiding it from others, making it sound almost unbelievable. As the rumor grew, Horie became increasingly obsessed, until it consumed his entire daily life. Day after day, he searched for glimpses of Yuriko Shio, the woman at the heart of the rumor, following her from behind, chasing her shadow. Driven by desire and curiosity, he continued pursuing her, beginning a secret journey into uncovering her hidden truth.
