It's a short story, only a few chapters.
Reading sadistic novels makes me vomit blood, especially when the female protagonist is physically and mentally abused and the male protagonist just apologizes and becomes so angry...
So all the beating, scolding, and humiliation of digging out the heart, kidneys, uterus, abortion, etc. Were all in vain, right?
I... Grass (a plant)
Based on the above, this is a piece of crazy self-pleasure that has no logic, no three views, and is tortured for the sake of torture (the male protagonist of the torture novel).
I don't really like to write plots about abusing the female protagonist, so I briefly mentioned the heroine's experience before she turned black. If any friends feel that the male protagonist is pitiful because of this, they can find a sadistic article and read it, and then introduce it to the male protagonist.
Purpose: Don't do to others what you don't want others to do to you
