Becoming the Guide of the Mysophobic Villain? Absolutely Not!

I found myself inside a simulation game set in a ‘Guideverse’ world. I’m supposed to be a Guide, but I’m an extra who can hide her abilities! Since it’s come to this, should I try living a sweet life with an attractive and talented Esper who suits my taste? Just as I was about to go all-in, I discovered a super handsome guy on the brink of a rampage and guided him passionately with a kiss. Now, all that’s left is our hundred-year journey together as he falls for my amazing guiding, right? …Or so I thought. As it turns out, I made a mistake and guided the Esper who was none other than the world’s most powerful villainous mastermind, the black-hearted master of this universe?
