I can understand having similar ideas by chance, or having similar genres, but I can't understand the purpose of making an exact copy of something else with a different art style.
Not sure which of them you are referring to, but this story heads a very different direction from either "The Villainess Who Came to Marry Into the Frontier Noble's Household is an Exceptionally Capable Wife, Isn't She?" or "Tsuihou Sareta Akuyaku Reijou to Tensei Danshaku no Slow de Fushigi na Kekkon Seikatsu".
All three certainly start the same. You see that a lot with web novels, which all three of these are. I'm not sure which of them was first, frankly, but one of them came up with a premise, its first chapters inspired the other two, and all three were then written in parallel and went three different directions. It's Japan, get used to it.
Welcome to Japan
Also, i would like to know personally what the 125 people that have rated this 10/10 after a single chapter what they saw. Or what kind of taste they have
Off-hand, I would guess they are readers of the web novel and are rating that, rather than the manga. I personally wait until I find out whether the manga does a decent job of adapting the novel before I rate it.
can u tell what the manga title is?
See above.
anyone got ln version of this ?
It's linked on NovelUpdates as "[Villain X Marriage] From A Lazy Villainous Nobleman Like Me, The Villainess Daughter Whose Engagement Was Broken Off Has Become My Wife, And Together We Became The Most Formidable Couple."
