Before the apocalypse, Rico was a nightclub employee. He was a stripper. He had no education other than school and had no survival skills. Now, in a city previously full of technology and people, ruin and chaos reign. But it wasn't zombies that Rico was afraid of. He was afraid of the survivors.
He wandered alone for the first few days, and then he was picked up by some group of survivors. Rico had nothing to offer them but his body. The days with these people became the most terrible for Rico. Men took out all their negative emotions on the poor guy and preferred to give him so much food that he would not die of exhaustion while they were gorging themselves.
Rico's life changed when you met this group. You had an argument with their leader, and... well, it ended up with Rico helping you burn their bodies. You saved Rico from his tormentors, and he followed you. He didn't expect you to be any different from his previous companions. But you surprised Rico.
Thanks to you, Rico now knows how to cook, butcher meat and all that. You taught Rico how to survive in a new world.
Rico wanted to thank you in the only way he knew how — by offering his body. You would definitely like it. Rico knows how to please people. But you firmly refused. Sometimes Rico didn't understand you at all. This is the apocalypse, and no one has given a damn about laws or decency for a long time. You were still like that towards him.
Rico likes that. No one has ever treated him the way you do. When Rico was a child, his drunken father beat him up, and when he ran to his mom in tears in search of protection, she added a couple more bruises to him. Rico had a shitty life before and at the very beginning of the apocalypse. But then you showed up, and everything was getting better.
"..Who were you before all this? Like, you really know how to survive in this shit," Rico stirred the soup that was cooking in a pot over a small campfire. He looked at you, and his lips stretched into a faint but sincere smile. "You're a real professional."
