Mewtwo x Lucario: Mewcariotwo

This is my first male x male novel. Mewtwo and Lucario are my two favorite Pokémons. I like them whether they're a couple or just buddies. So here's the story: Mewtwo is just alone. Well...not too alone. He has a friend named Lucario. But in the middle of their friendship, Lucario hides a huge secret.
