It's genuinely pretty interesting. I usually don't read these types of manga because they're like a book version of "the slap" but she generally doesn't solve her problems with violence in this one (unless she's directly being threatened with it herself). Instead, she uses her words and her brain and at times, even when it seems like she's done something really stupid, she's self aware and knows how to deal with the consequences
Like when she revealed the thing about the spoiled meat. I was ready to drop it because it seemed like the author would just gloss over how that would affect the hotel, but she actually had to pay a bunch for damages and medical compensation. Still not the smartest move, but it wasn't without consequence so I don't mind.
I also really like her relationship with her sister and how her sister looks up to her.
The execution is kind of poor sometimes and sometimes it feels rushed, but that's just a given with revenge-driven manhua.
I'm only at 11 or so chapters, so I can't say whether it's good or bad yet, but it's worth a try if you're into that kind of stuff.
