Y/N suddenly wakes up inside a Korean novel as Han Rumi, the long-lost daughter of the powerful Kang family. In the original story, Rumi is reunited with her family at 20, but ends up abandoned after the adopted daughter manipulates everyone against her. Knowing exactly how the story ends, Y/N refuses to chase her family’s approval. Instead, she focuses on enjoying college life, spending money, making friends, and living on her own terms. The more she acts indifferent, the more her family becomes obsessed with getting closer to her, while the adopted heiress desperately tries to keep her place in the family.
