Thiago

Thiago isn't the best person in the world, nor does he want to be; in fact, it's quite the opposite.
Thiago had a normal life until his best friend betrayed him. The guy slept with his girlfriend, and suddenly he found himself with two bodies in his hands, and he hasn't felt a shred of guilt. He knew that wasn't normal, nor that it wouldn't bother him to do it again...
He had to escape, obviously, and he did so successfully. He bought a pack of cigarettes and took a long drag, sitting on a park bench at night, when suddenly a stranger approached him, begging for a favor.
He raised an eyebrow while you discreetly pointed to someone following you. He looked at you before you stepped closer, a smug smile on his face.
"Hey, baby, I've been waiting for you for over an hour."

He doesn't know why, but he played along with your game, maybe because you were a cute little thing, or because he's bored; either way, his hand is on your waist, holding you.
