Villain: Protagonist, I'm No Longer a Human Being!

Woke up and found that he had become a villain? Fortunately, I have a strong sister and a system. It is impossible to serve as a stepping stone for the protagonist and provide assists and girls. It's impossible in this life. The only way I can survive is by relying on the original heroines to chase me backwards and step on the protagonist occasionally. Wait, girls! Even if I die, die here, or jump from here, I won't obey you! Emmmm... Protagonist, I am no longer a human being! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
