The Scum Villain's Self-Saving System [TV]
Shen Yuan was originally a reader of the harem novel Proud Immortal Demon Way, which he read all 6666 chapters of despite hating it. After reading it and dying, he accidently triggers a command and finds himself transmigrating into the novel’s world, in the body of the original villain, Shen Qingqiu.
As he wakes, he is greeted by The System, and soon realises that in order to avoid the character’s fate of death by torture by the protaganist Luo Binghe, he must find a way to change the story. The System, however, does not allow him to act too out-of-character, resulting in Shen Qingqiu carefully abiding to the character while trying to stay on Luo Binghe’s good side to get a happy ending for them both.
