Her mother always fights with her (fondly) and complains about her being weird and having a bad temper but both her and her dad remember how much she did for them to be able to live well and feel guilty about letting her suffer so much in her childhood, so even though they were very humble and traditional, they still kept her room at home unoccupied and promised her she'd always have a place with them. They visited her constantly to take care of her and pretty much had daily visits with their married daughter and the in-laws family because they really loved her and she was more important than following the "proper" way to get along with a married daughter.

For once, the whole novel is set in a village and at most they go to the nearby town or prefecture. ML is not interested into becoming a powerful minister. He becomes a magistrate but only uses the 3 year period to make some laws and build projects to protect little girls and give opportunities to homeless or ab*sed children then resigns because he's happier devoting himself to his family and eventually inheriting the family businesses from his rich grandparents. MC feels guilty depending on ML's rich family so she gets a business partner in food business and becomes the "brain" of the operation to get some dividends which she uses to open women's schools and houses to educate and offer job opportunities to suffering children, she also teaches a modern recipe to her mother so she could open a food stall and have a reliable income. It's pretty realistic.

The system is hateful and for some unknown reason only communicates while she's sleeping and not conscious enough to decide or answer so it always chooses "by default". The mission (that is, ML intentionally killing MC) was pretty much impossible but the whole existence or purpose of the system was never explained. It only served to push MC into bullying ML and later for the short angsty part where lies about cheating on him and divorces to provoke him. Then it disappeared all of sudden after she failed the mission but the system is so malicious... taking that into account, how can she rest assured about her body being replaced and accompanying her beloved dad in the other world? Also, the whole "cheating and divorcing" plan was extremely st*pid, she knew him well enough to know he'd never harm her in anger. Her best chance was probably just a mercy killing but she never really considered other methods
