I don't think the original story had her existence in it. Her brother existed but not her.
I'm guessing she saving him as child messed up the story somehow such that Leto stopped being the ML and Ignis became the ML.
But Leto is still a yandere with mental development problems, so I don't really expect him to go away.
Remember the MC did say that Leto had to be taught by the heroine of the original novel how to live correctly.
Her entire existence is throwing the story out of wack. Her brother were supposed to be good enough to be one of Ignis personal guards but her being an Olympic champion in her previous life slowly created an inferiority complex in her brother.
Then that inferiority complex and the similar situation that his lover has with his father made him decide to try to be useful to at least one person in his life.
Every other story like this is written in such that the MC is reincarnated and
possessing another character's body.
This one on the other hand, the MC got a new body. She's not possessing anyone.
