The Idiot Killer Is About to Counterattack

Wearing books + growth-oriented heroine + sadomasochism + stand-in literature + villain with super high IQ Su Yirou inexplicably traveled to the world of book spirits. At this time, she didn't know how miserable her future would be. First he was transformed into a killer, and he kept running away but never succeeded. Later, she learned that she was summoned by someone, and the person being summoned was not her at all. She was an accident. Substitute, bewitched, poisoned, imprisoned, amnesia, dementia. She originally thought that her life would be like this, but she never thought that someone would risk their own lives to save her, even if it cost them their lives.
