The war backdrop doesn't feel real when all the characters are caricatures.

She literally turns from super pro-active heroine into your ideal housewife who waits at home, does nothing except clean the house, cook, and pine for her husband to come back from "war."

Blegh.

Author tries to make the whole thing better by talking about the role reversal as the MC's mom used to be the one going out and around while her dad stayed at home waiting for her mom to come back, which doesn't work because: her dad runs his own big business "at home" raising and training mythical creatures.

MC doesn't have any hobbies and simply goes from "girl who represents her dad's company and takes creatures around and travels all over" to "wife sitting at home waiting for husband to come back for 4 years, " which sounds like the author totally forgot the whole premise at the start of the story.

Adds to why I don't think this is josei, since the MC thinks that being 20+ is "super old", which makes this shoujo.

Taken from chapter 2:

“Just say it.” Zhen Hong Sheng, seeing her wanting to say something but unable to, hastily hinted that she tell the truth bravely. He has always very attentive about his own appearance, and he perked his eyes to hear her evaluation.

Very seriously, Xin Mei said, “You look like a woman. I don’t like the pretty types.”

I am really bothered the fact that ML mother obliterated her husband family. At first I thought they don't give af about human life but the characters cares their own clan. So maybe they don't give af about innocent life except their own. If what the mother said is true, the father also don't give af about his own family members.
