Yua has hated her father-in-law Taku since she got married, she has no choice but to accept the situation and the bastard, and resorts to drinking more and more wine.

He takes advantage of her son being on a business trip to make a definitive approach. Took some convincing and spiking her wine but he finally succeeded.
