Yandere-kei Otomege no Sekai ni Tensei Shite Shimatta You Desu
Lycoris, as a precocious child, suffers from a strange sense of deja vu. On the day her father told her about her fiancé, she realizes that said fiancé was actually a character from an otome game she once played in her previous life.
“I got the heroine’s rival position? The type of girl that often gets stabbed to death in a bad ending? No way”
This protagonist endeavors to avoid the yanderes all around.
