Cheng Shuyu is a good student with excellent academic performance, pure and lovely, kind and lively, civilized and polite, all of these are true; she is also a highly poisonous poppy, giving people a fatal threat and temptation, and all of this is true.
Gu Sichen was deeply attracted by this aspect of her, even though her hands were stained with blood, and even though the only thing she liked about him was her pathological possessiveness, he had no regrets.
If Cheng Shuyu was destined to be his poison, then he would be willing to die.
