Su Chacha has been living inside a novel for three years, but her wicked female supporting character system has only just activated. Unfortunately, the entire storyline has already gone wildly off course ahead of schedule: the true heiress, her younger sister Lin Wanwan, has returned home, her fiancé refuses to follow the script, and the mysterious Gu Nian is secretly rewriting reality and erasing memories. But Su Chacha refuses to follow the usual path of humiliating the villainess. Instead, she delivers sharp-tongued commentary while using livestreams, contracts, and group messages to create anchors for her memories, fighting back against the system's attempts to correct the storyline. Then, when the experimental records of Subject No. 7 come to light, she realizes that the memories she has of entering a novel might have been fabricated from the very beginning.
