For me it feels more like some of the characters aren't revealed, and purposefully so. Like Chairwoman Cha's husband, Sia's older brother (and how Chairwoman Cha keeps defending him), Yohan's husband, Siheon(?)'s husband and children...
For me, the story ties itself up in a good enough bow, but the hidden characters were annoying. Just gonna say the author was lazy for that lol

It has a very middle of the road story, lots of things left unsaid. Some may enjoy it more than others.
It didn't feel like it had much meat on its bones in terms of story, cliche plot twist etc.
I would recommend this to people looking for a story of a female dom, simple plot, quick read.
