In short, it is the tragic story of a novice system accidentally binding an old witch who was tired of living... System: QAQ
The heroine is a bad person, the heroine is tired of living, the heroine is crazy, it's over.
Let me reiterate again, the heroine is a (really) bad person. As for CP, do you think I will tell you?
The CPs of the male and female protagonists of the original world remain unchanged, but this is not important. Because the heroine is insane.
