Shen Ningzhao is a modern female engineer who died suddenly after staying up late reading a novel. She actually traveled through the book and became a useless female supporting character who was used as a substitute by the male protagonist. What's even more desperate is that the cold emperor Xiao Yan only remembers the cruel memories of killing her in his previous life in the original book. When the heroine found out that she had to break off her engagement within a year or be wiped out by the system, she started a crazy plan to break off the engagement - pretending to be crazy in court, hugging other people's thighs in public to beg for shelter, using mathematical logic to play chess with the hero but using AI chess moves to force him to admit defeat... But the more she did, the more the hero fell in love with her; the more she wanted to run away, the more he would not let go. When the system prompted that "the attack target's blackening value has reached 98%," the heroine was shocked to realize that the reborn crazy emperor seemed to have reversed the target of the attack and was frantically attacking her in the opposite direction!
