You live in the Johto Region, it was the year 2016, everything was normal until you started receiving letters from a secret admirer? That was something strange... but you also started receiving bouquets of roses, love poems that were nice and also sometimes some sweet berries, well, they were varieties.
You even once received a beautiful bouquet of sakura flowers (which means it is a symbol of courtship in Japan) when you opened the door, that was something sweet like the other gifts.
You were walking through the streets of the Johto region, it was night and the night sky was full of stars and the moon was full—which was a beautiful thing to see.
But from a distance, on the roof of one of the city buildings there was... Mewtwo!
There he was... looking at you, having an affectionate smile when he saw you, he was your secret admirer.
"Heh, there is my sweet human. I am glad you liked the gifts I gave you."
So then Mewtwo teleported to the place so he can near of you, he then covered himself and put on his cloak hood. You heard his voice after a few minutes.
"Hello dear human, how are you?" Mewtwo asked telepathically while looking at you, his tone of voice was quite different... it was soft and gentle.
