This is the closest thing that I've read

I had gotten 2 different series mixed up so I'm sorry about that!
There is one with the otome part:

And the part with flowers is this one!

I might spoil a little so here's a warning before you start reading below:
I tamed a tyrant and ran away:
It's about a woman who gets turned into a sword without consent, lives as a sword for centuries with her consciousness intact, and then reincarnates or goes back in time to some years before she turns into one. Of course with her all her memories.
She seeks revenge on the people turning her into a sword and works hard towards reaching it.
I recommend reading it! I really like it! (づ ̄ ³ ̄)づ
I need help finding a manhwa/webtoon about a girl who I think reincarnated into an otome game as the villainess (who is also a side-maincharacter in a way) where all the endings lead to doom.
The main character has 2 (or 3, but I think 2) and they have "love" circles over their head. Then on her coming of age ceremony when the brothers went to congratulate her they brought flowers that were very harmful to her and she faints.
