It's unfortunate that it had such a great start, great potential, but it all goes kinda downhill.
The art looked amazing in the beginning chapters. A bit like watercolor and the art definitely had its own unique style. But as the story progressed... it became the typical, good art that a lot manhwas have. Unfortunate. Understandably, it takes a lot of time and effort to create that unique art style from the beginning chapters, but the change was really disappointing to me.
The first chapter really hooked me in. I liked the protagonist Rosaline and the way she was portrayed. Strong, smart, neglected by her family, but still felt responsibility and duty towards them. That feeling kinda changed, but then towards the last fifth (?) of the comic, I changed my mind again.
Thinking over the entirety of the comic, I think the storytelling quality really peaked in the beginning chapters. The story does get interesting towards the end, though I'm no longer much interested in the characters.
SPOILERS As much as I like OP and cool characters, I didn't much like how Rosaline became... so OP in her role as duchess. Part of it might be due to the storytelling. They kept using that technique where readers only see hints of the character's plan until it's revealed in the very end of solving the problem. They must have done that at least 3 times.
So... yeah. I would've told my past self to pass it over.
