My advice: Read at least 10 chapters (preferably the first 20 chapters), and then re-read the first 10 chapters, before deciding to continue it or not.
I say this because the first 10 chapters or so can be confusing when you start reading this due to the fact that there is constant "time-reversal and retelling events through the same period of time" occurring in the first few chapters without any explanation; so while the story is still interesting, the first read through can be rather confusing.
The confusion arises because time reversal is a main plot point for the story, such that in one chapter someone may already be dead, in the next chapter they're alive, in the next chapter they may be appearing just as a figment of someone's dream, etc. Additionally, there are many similarities across chapters, and nothing specifies that time reversal has occurred or gives specifics about "when" time reversed or why. So the information you get from the first few chapters is a bid hard to interpret until after you finally get into the chapters that are relaying (what appears to be) the "current" run-through of this period of time. --- I feel like just trying to explain it is a bit confusing too, haha.
Otherwise, the art is full color and pretty decent. I'd give the art alone 3/5 stars; it's appealing enough to be called "good". (I've seen better/more detailed/more artistic works that I'd give 4 stars ['Beatrice', for example, is somewhere around a high 4 to me], and I'd save 5 stars for something that was clearly gorgeous or somehow just artistically "worked' aesthetically with the story.)
Regarding story, it is a bit early to say one way or another whether it is 'good' or 'bad'. For now, I will say that there are no glaring cliches or trite plot developments that are like the flea infestation of comics, manga, manhwa, and manwha. The time reversal and re-living the same time period aspect is interesting. The origin story of a dragon that fell in love with a human, and then reversed time after her death to live again with her may not be a completely new idea, but it doesn't feel like a cheap plot device. The dynamics between the FL (who is "strong" regardless of timeline; Intelligent, capable, ambitious, noble, and courageous - determined to be a great Duchess or a Knight or whatever she must be to face an OP foe, depending on the timeline), her younger brother (who suffers PTSD courtesy of the ML, and must face the ML despite his trauma) and father (who kinda seems like 'Schrödinger's Cat' thanks to the time reversals), the OP ML (the second prince; probably a descendent, remnant, or reincarnation of the time-reversing Dragon), and the minor characters are interesting to see.
I look forward to reading more, and to be honest I'm pretty sure I'll end up re-reading the first few chapters for a third time just because there's a lot to take in about how Lamia lived her lives, and how many times Lamia has died causing a time-reversal to trigger.
