In order to change the fate of Giselle, who has been reincarnated as an elder sister of a villain's daughter, she is destined for ruin or death! In order to change her fate, she begins to reeducate her younger sister, who is the most responsible of all things. Then one day, the Marquis Cask family invited her to a tea party. If it is Cask, it is the house where there are the fallen brothers who are the target of capture (and the younger brother will be Giselle's fiance). I'M GOING TO SAY GOOD-BYE HERE. MY YOUNGER SISTER WILL BE ABLE TO STEP THROUGH THEIR MINES?
