I 3-seneun Angnyeogimnida

"Just why do I have to possess someone who’s already possessed...?!" I became the female lead in the novel "I Possessed the Villain’s Granddaughter", who is already possessed. But the truth is, she’s actually the villainess who will torment the real heroine. What do you mean I’ve become the villainess who will suffer terribly for harassing the heroine? I can’t believe it! My fate was sealed to become trash before I knew it! I can’t live like this! (Source: KakaoPage, translated) *Note: This is a promotional one-shot for the web novel of the same name.*
