Because her husband does business far away, he often doesn't come home, which makes his wife very sad but still understanding towards her husband. Knowing that her son is not at home, the father often comes to visit, "caring" for his daughter-in-law.
One time, seeing his daughter-in-law sleeping with a tired face, the cunning old fox pretended to come and check this and that, as if he was very worried about his son's wife, but inside he had another dark scheme…
With no husband at home, the young girl was naive and trusting, of course, the plan to "consume" the beautiful daughter-in-law of the old father-in-law was successful. What a despicable old man.
