I was reincarnated as the heiress of a conglomerate in the novel. However there was a problem, this world was about to be destroyed by a virus monster. All I have left is money, I quickly bought in the countryside and built a shelter to avoid monsters…The world went down much faster than I expected, f*ck! And somehow, even the male leads are trapped with me in my house. But it doesn’t seem like these two wanted to leave. Why is it as if you guys have no intention of going to the female lead? “What the hell are you?” “I think she knew about the fact that the world would be destroyed.” They had a lot of questions for me but I couldn’t answer them.

So, let’s roll the male leads until then and hold out! But there’s one problem. This old mansion I bought turned out to be quite suspicious. What the hell is going on in my house?

A serious accident caused the protagonist’s brain to have an unusual mutation. This changed the brain development that it opened the door to a mysterious universe. Not only he obtained a ‘god-like’ powerful telekinetic control and mental perception, he also had an abnormal analysis and memory capability comparable to super computer. Having such super brain, his rough life began.
