The MC and her sister are embroiled in a "war" within the household, where each tries to bring the other down - our MC for survival and revenge, the sister out of jealousy. This leads to a host of schemes, including - but not limited to - sending maids as spies, sabotaging each other, attempting to steal the fiancé, trying to ruin each other's social reputation, and trying to impress the father of the family.
Some schemes fail, others succeed, just like in real life. Each action has a consequence, and (as far as I can see) nothing is forgotten. Along the way, we meet a host of other characters: supporters, antagonists, extras, and neutral parties.
Personally, I'm a huge fan of political intrigue and strong female characters, and in this story you get both.
The MC is constantly looking for ways to win and survive, never getting side-tracked or forgetting her objective like in other manwha I've read. While she does experience setbacks, she never lets them bring her down for long, instead finding ways to profit or learn from it. The MC feels very "natural" in general; it's not hard for me to imagine that someone would behave like this after everything that happened in her past life.
So far, there hasn't been a lot of romance for the MC, but the hints that we get feel very organic. All characters seem well-rounded and their actions understandable - so far, nobody behaved in a way that I absolutely couldn't get where it came from.
I definitely recommend that you at least check it out, I haven't regretted it.
