Recently, Yuna had been feeling down, suspecting her husband of cheating. One day, a repairman came by to fix her drainpipe and ended up raping her—but deep down, she felt a hint of pleasure. Neglected by her husband, she had grown increasingly lonely. Soon, her heart became captivated by someone else. When her husband's colleague, Oki, stayed over, his kindness stirred desire within her once more. Unable to control herself, she gave in and passionately fucked him right away. Yuna, who had already begun questioning her marriage, now found herself drawn toward this new relationship.
