Raped by my father-in-law... Beautiful wife playing

Koi, a wife, was fired from the company where her husband, Isao, worked, and moved to Tokyo to rely on her husband's family home. Yang, her father-in-law, was a novelist and a very kind and intelligent man. By chance, Koi ends up helping her father-in-law with his work. Yang was kind at first, but took advantage of Isao's absence and did something obscene to his love... She can't even confide in her husband and spends her days worrying alone. However, with no other destination for Koi, she had no choice but to follow her father-in-law's orders.
