“The masterminds are cooler than heroes,” I mutter as I stare at the chess pieces before me. It is easier to be the one who sits in the shadows and moves the pieces, likewise deciding the flow of the game.Heroes will foolishly sacrifice their lives for the good cause and villains will sacrifice the world for their own gain, but masterminds will use both the heroes and villains to their own benefit.Why, you ask? Well, that's because I've lost my life once while trying to be a hero so, I don't want that anymore. I'd rather be a mastermind who molds the world as per my convenience and live peacefully.

I mean who in their sane mind would want to mess with the complicated royal family and political affairs? But that's not all though.I've also become the saviour of this world. Things just can't be anymore worse!Besides, the penalty of failing this quest is...[Failure: Destruction of the World.]It seems like if I screw up in selecting the right person then the destruction that is going to befall the world won't be stopped.If I speak of my reward then it's this vague thing.[Reward: Fulfillment of any wish.]“If that's the case then, I'd rather choose the person who would be the best fit for the throne.”And that's how I decided that I would become the Kingmaker.

He’s the dream guy of women world wide, the CEO of a formidable mega-corporation. But, he’s absolutely powerless against her, resorting to all kinds of methods to force her into a marriage, tying her to his side with a certficiate.
