My Girlfriend and I Are Antagonists

I traveled through time and became a villain. Forget about being a villain, I originally thought I could have a great time and drink, but... My girlfriend also traveled through time, and this and this... Later, she is also a villain, damn, worse than me. Why does she want to accept a male favorite? No, I have to stop him. As a villain in this unknown plane, watch how I use the novel routines I read in my previous life to kill those fateful pig's feet, haha, I'm lucky and I'm not lucky, uh uh uh, does it sound like a villain? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
