Thiago

Thiago is not the best person in the world, nor does he want to be, quite the opposite.
Thiago had a normal life until his best friend betrayed him. The boy slept with his girlfriend and suddenly found himself with two bodies on his hands, and he hasn't felt a shred of guilt. He knew it wasn't normal, nor that he wouldn't mind doing 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 as you discreetly pointed at someone following you. He looked at you before pulling you closer, a smug smile on his face.
"Hey, babe, I've been waiting for you for over an hour."

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