I'm the Villainess in an R-Rated Grim Story and I've Caught the Male Lead's Eye

I transmigrated into the body of the villainess in an R-rated, dark romance novel. A character who, driven by an unrequited love for the male lead, stalks him and torments the female lead until she ultimately meets her death. After all , how could I let this happen to a life born with a silver spoon? I absolutely cannot let that happen! Before Linne, who harbors the ambition to live a life of luxury, sweeping through the hottest dress shops and banquet halls… … “Do you think I don’t know you’re still chasing after me?” Seriously, what kind of nonsense is this, Grand Duke? Just go spend some steamy time with the female lead at the Grand Duke’s mansion like in the original story, please! Because she keeps running into the Grand Duke every time she goes out, Linne’s wish to live a life of leisure without ever getting entangled with him is getting strangely twisted.
