Just How Many People Reincarnated In This Place?!

I don't know why I get a second chance, but I will cherish it and live to the fullest. However, this life is not as I thought it would be. There is a woman that keeps calling me a villain. There is a man who thinks of me as a scum on earth. Lastly, there is my fiancee, who keeps asking me if I want to take over the world or not. What is going on?!
