我妻姉弟 背徳編
Yuji is living a double life, maintaining a relationship with his girlfriend while also carrying on an affair with her mother. Yet despite these entanglements, his thoughts keep drifting back to his sister, Aya. He tries to bury his forbidden desires deep inside, convincing himself that what he feels is nothing more than sibling affection. But the more he suppresses his true feelings, the stronger they become, haunting him in quiet moments and fueling his guilt.
As Yuji continues to deceive himself, his sister Aya remains a constant presence in his life, unaware of the turmoil she stirs within him. The tension between his public persona and his hidden cravings grows unbearable. He must choose between the safety of his current relationships and the dangerous pull of his blood ties. But every step he takes toward Aya brings him closer to a point of no return, where the boundaries of family and desire will shatter forever.
