The Scum Villain’s Self-Saving System

After Shen Yuan dies in the real world, he wakes to find that he has transmigrated into the world of Proud Immortal Demon Way, a stallion or harem novel he hated (but nonetheless read all 1000+ chapters of). As he awakens, he's cheerfully welcomed by The System, who tells him his "account" is now bound to the character Shen Qingqiu, the original villain of the novel. He realizes he has to change the story to avoid being tortured to death by the main character, Luo Binghe. But The System has other ideas, not allowing him to act too out-of-character to avoid derailing the plot. What follows is a delicate balancing act of Shen Qingqiu trying to stay true to his character while trying to ensure Luo Binghe has the happy ending he always felt he deserved. (Source: Fanlore)
