i will become the villains poison taster

I, an innocent office worker, possessed a character in the devastating novel *The Poisoned Apple*. On top of that, I'm Giselle Lloydsvin, a villainess who gets poisoned to death before being hanged! But the poison brought by the assassins doesn't work? It even tastes like fruit! "You'll be okay since it's only a little bit, so hurry and drink it." …Even though I possessed someone, it seems my destiny is to be tormented by a crazy assassin. However, "Leniel", who I thought was just a crazy assassin, turns out to be the frontman for the final villain, "Wayne Ayore"?! In order to hold onto this lifeline, I clung to the villain in *The Poisoned Apple*. "I can distinguish the taste of poison." “Poison?” “Yes.” “What use is that?” “Your boss is going to be poisoned, so I can be his poison taster.” And so, I thought I could survive well as a general store employee of the villain’s frontman(?)... “My boss is so strong to the point that there’s something suspicious about him!” …Why does it feel like I’m doomed in this life too?
