A bored person sacrifice's his life by saving someone from getting hit by a truck because of boredom, gets reincarnated in Hamefura: My next life as a villainess as Katarina's Butler. (It's up to you to make whatever kind of plot your going to do, wether Katarina didn't get the memories of her past life or adding a women reincarnated but the women only knows the world as an otome game, just like Katarina.)
