First-anime-verse, because I like Envy's backstory there. This one took me FOREVER to come up with, and it's pretty weak as far as the theme goes. I like the story itself, though :X
3. The Dawn
"Ha-ha! You think you can run from me, shrimp?" Fullmetal had made the mistake of running down a dead-end – and Envy knew this particular town like the back of his hand.
Ed growled, clapping his hands together – but before he could touch them to anything, Envy had his wrists pinned to the wall.
"Now, now, none of that, my naughty little alchemist."
"DON'T CALL ME LITTLE, YOU SCREWED-UP PSYCHOPLANT!" Ed struggled and kicked, but to no avail. "Fuck, how the hell can you be that strong when you're the size of a twig?"
"Practice, darling. Now, how do you want to die – quickly, slowly, or extra slowly?" Envy grinned. "See, I'm being nice. I'm giving you a choice."
Ed scowled. "Stop calling me weird names, it's creepy as fuck."
"You don't know how creepy, beansprout."
Envy expected another short rant. What he got were a pair of lips firmly wedged over his own in an amateurish and slightly misaimed, though unexpectedly passionate, kiss.
He let his eyes slide closed as he sank into the kiss, coaxing the younger boy's mouth open with his tongue. Oh gods above…
- and suddenly he was hanging in mid-air as Ed wrenched himself from the sin's slackened grip and darted down the alley.
"I KNEW YOU WERE A CREEP!" yelled the alchemist, before sealing off the alley with a wall and ceiling of stone.
Envy sank to the ground, too stunned to continue the chase as realization dawned. "You've made a fool of me, alchemist," he whispered, unable to muster his usual harshness. "You've made a damn fool out of me, and you're gonna regret it."
He never quite saw Fullmetal the same after that. It was, in fact, the dawn of a whole new stage of his obsession.
