It's too early to say 'there's no real suspense, we can predict everything bla blah'
Read the novel, you might change your mind https://woopread.com/series/the-villainess-is-a-marionette/
When you've read a lot of webtoon or manga in the isekai genre, you quickly understand what's going to happen and you can even predict what the heroine will do !! I prefer originality so I quickly become critical !!
Afterwards you are probably right, I think the best it is that I read the novel, it will surely be more interesting.
Thanks for the link

The art is so stunning!! Gosh . Aside from the drawings, I find the plot a bit weird. Without the beautiful designs, this webtoon would be pointless in my opinion.
Already we do not know if it is a transmigration in a novel or if it is a journey back in time. Besides, isn't it a bit too easy for her? She just needs to say something to make people believe her even if they have a little doubt. And yet, everything she plans always goes in the direction she has decided, for me it is too simple.
Honestly, there is no real suspense, we can predict everything that is going to happen so it is boring.
Well, I don't understand why she doesn't respect the old Cayena, okay she was a spoiled child but from there to calling her a bitch and pretending that the old Cayena
bothers her, I want to say her that without the body of the old Cayena, she couldn't live again so she would have to show respect. Maybe the problem is with the translation too ...
In short, it was just my opinion.
