So, this story deviates a bit from your typical manhwa. Fair warning: if you're not looking to read about a disfunctional relationship with a dark, manipulative male lead, this might not be the right story for you. Then again, the story doesn't try to dress this as anything other than what it is: the monstrous result borne from a life of terrible trauma and mental and physical abuse -- and that's what drew me to it in the first place.
If there's something that can be said about this work, is that it's full of passion. Rather than the typical isekai story, where a downtrodden female lead gets a new chance at life, fulfilling every power fantasy its author might have, this manhwa (or webcomic?) does not make things easy for its characters. Each one, even the secondary ones, has great emotional depth, and the facial expressions convey a lot of emotion, as well. It constantly takes stabs at your heart, and does NOT pull any punches.
In the 27 chapters I've read, it's made me laugh -- and it's made me cry. And while it is true to female lead cries often, I, at least, can't help but sympathize with her. She's been dealt a pretty terrible hand, and what makes me like her is that -- yes, she cries a heck of a ton, but she also has a decisive personality, asserting her thoughts and feelings rather than letting herself be carried away by the circumstances.
The male lead is also interesting, and full of twisted personality. That's the thing, though: this manhwa doesn't dress this as "healthy and sweet". No, it's dark, it's raw -- they are obsessed with each other to a pathological point. Not something I would condone in real life, but as a story, it carries its themes wonderfully.
