Otome Game Rokkushuume, Automode ga Kiremashita.

The protagonist is reborn into an otome game as Mariabell Tempest, a noble with a harsh personality. Every time the heroine achieves a happy ending, Mariabell suffers a grim fate such as disgrace, disappearance, or death. An active auto-mode prevents her from making her own choices. During the sixth cycle, the auto-mode is turned off, allowing her to act freely. To survive and live safely, she must use what she learned from her previous five cycles. This manga adaptation is based on a fantasy-otome game reincarnation novel.
