I'm such a villain

When I woke up, Gao Fushuai set the start of Tianhu. But the system told me that I was not the protagonist, I was actually the villain. On top of that, I just captured one of the protagonist’s childhood sweethearts! Before I even begin to figure out the situation, I'm just confronting the protagonist? A reborn person in the city, an accomplished young man who came down from the mountains, the number one retired killer, wait, is Huang Rong next to him?
