PLEASE HELP ME FIND THIS ISEKAI VILLAINESS MANHWA

please help me remember the title of this manhwa (because my reading list got wiped).

so the story goes like this, the MC got isekaied and possessed the body of the villainess ... the circumstances when she possessed the body is that her younger stepbrother was still a small child ... their father who is an emperor is sick and bedridden and got indulged in vices especially wine ... the MC explained that in the novel ... that the villainess keep bullying the male lead who is her younger step brother since he was a child ... assassination attempts because the emperor was going to die soon and they are competing to usurp the throne ... the cycle of this violence repeats until the male lead became an adult and then the male lead already plans a coup and overthrown the empire ... and before the ending the male lead and his coup alread invaded and conquered the imperial palace and at the throne they met again with the villainess bus this time the male lead has a weapon pointed on the throat to the villainess and asks the villainess to say her last words before dying ... so this is what the main character explained the plot of the novel

so moving on, she wants to avoid that fate and wants to treat good his currently younger stepbrother and live quietly ... this is her plan ... along the way she met with the master of the magic tower and fell in love and plans to settle down with him ... but this is where the MC regrets her decision to settle down with the magic tower master because she explained in the novel that the magic tower has the reputation of wanting to have more power so they have the will to plan treason against the empire in which it is true that the magic tower master really plan treason then the plan was revealed ...so when the plan was revealed the empire and the magic tower had an internal war (well .... idk if this is the exact plot but you know the gist) and since the MC has a relationship with the master she was declared also to be an accomplice so eventually her fate is the same as the novel had created even though the plot is different the fate is the same ... she will still die by the hands of the younger stepbrother with the same way to die ... struck by the sword at the throat (or at the heart or chest idk i read it a while ago).


so when she died she reincarnated again at the time when she first possessed the body .. her younger stepbrother is a child again ... the emperor is alive but bedridden ... indulged with vices and sick and will die soon ... so she attempt again to go against that painful end so this 2nd time she did not get involved with the master of the magic tower ... but even if she didn't get acquainted with the magic tower master ... she still end up with the same fate but this time by another factor, so she still end up the same ending scene ... her younger stepbrother asks the mc her final words .... same way to die ... struck by the same sword ....

so when she died the 2nd time the emotional condition of the mc is already unstable she was starting to get tired and says things like she doesn't understand that why things end the same way the novel does ... stuff like that and gave up trying and felt furious, so during her 3rd 4th until 5th try she really acted like the villainess in the novel like on her 3rd to 5th life she started bullying her younger stepbrother even though he is a child ... she arranged assasination attempts to her younger stepbrother ... she really did what the character she possessed do in the novel because she doesn't care anymore ... she gave up trying ... even in the 5th try when the male lead asks her final words she was sitting at the throne nonchalantly and want to get this over with ... but she still isn't used to the painful sensation of being struck by a sword .. she is still scared of death

so on the 6th try she has the motivation again to go against her fate because after that 5th try she is still scared of being struck by a sword... so this time on the 6th try she will treat fairly her step younger brother again but vibe and demenor is ... she is very chill, calm, and act mature unlike on her 1st life where she acts like a jolly teenager when he treats her younger stepbrother ... but here's the twist in this 6th life of hers ... remember that magic tower master she got involved with on her first life? they met again but the time the MC immediately pushes him away ... but then what's weird is the master is like begging the MC to forgive him for what he did which is weird because in that 6th life this is their first time meeting so she speculates that the magic tower master go along with the reincarnation .


so that's all what I remember I think the real story starts on her 6th life the previous ones were preludes or early few chapters ...to help find this manhwa further I remember the younger step brother has a blue green hair color idk tho i forgot... i want help because there are already do many villainess stories in the library that it's hard to find.
