She is a intelligent girl who deeply loves her man and doesn't want anyone else to have him.
She reincarnates into a novel I believe, just looking to run away from her death flag, and she oddly attracts some characters pretty easily.
The mc reincarnates into a mostly crazy otome game. She is a intelligent girl because she knows of the future. She easily attracts all the male characters with just her kindness. Along the way she really just wants to stop all the death flags/flags in general.
