"You must absolutely not move... I'm the one at fault," Ririka Kinoshita, my wife's friend, suddenly whispered, instantly shattering my composure. She secretly shoots me burning glances, staring intently whenever she can slip past my wife's notice. I'd be lying if I said I hadn't noticed—her seduction grows more intense each day. I know it's wrong to get involved with my wife's friend. Yet, I'm powerless against Ririka's overwhelming allure, my heart gradually being stolen away. Each step forward pulls me deeper into her web of temptation.
