SPOILERS: So i read a summary of the novel and turns out the fl is a transmigrator from korea, she is stuck in the body of daphne and wants to go back to the real world, but no matter what she does the story keeps rewinding. So after countles tries she goes mad and kills everyone, each life she kills a different person to try and break the cycle. In one of those lives she told the ml the truth about this being the world from a novel and since then the ml has gained awareness and remembers each life after rewinding, he has been stuck on the same cycle for hundreds of times.
Blablabla going to the last chapters they figure out that what was keeping the fl stuck in that body was the devotion and love from the mc so when he finally accepted the truth about her being a villainess and killing her, they break the cycle. Everything goes back to normal and the fl goes back to korea and daphne is erased from the novel's story.
After that we get some extra chapters with ml and mc being lovey dovey

Can someone confirm if this is true or not ? I saw a TikTok spoiler comment about this manhwa saying that FL is aware of everything and is a villain and whenever she gets bored or whatever after marrying the guy she just khs to restart everything?
