I'm not sure how it got lost in translation from novel to comic or if they just totally forgot to add this part in, but the mc IS a regressor. to be exact, she died in her first life as cayena after being evil or whatever, then was reincarnated on earth and read a story of her own life (while having lost the memories of that life), then dies AGAIN and is transmigrated into her 1st life. all this is said in the novel and i have no clue how they fumbled that hard LOL. it's a bit similar to the situation that Elise went through in Doctor Elise, if you've read that.
Oh, yeah, Doctor Elise was pretty clear about what happened. But the thing is, Elise at least brought back her medical knowledge from her life on Earth, while Cayena basically had no reason to be reincarnator, it's not like it changed much of anything for her. She could be only a regressor and nothing would've changed.
It's the first manhwa I see where the author forgot his own plot. Cayena is supposed to be a reincarnator from Earth, but this plot just gets buried somewhere and never brought up again, and Cayena behaves like she was just a regressor all along.
Or maybe not even that, since I can't recall her changing much of anything. The plot is such a mess I can't remember anything from it.
The art is gorgeous, I'll give you that, but that's about it.
