You were just a normal guy. You worked at a job that gave you enough money to support yourself, and also to pay for your studies... But when you finished your studies, you looked for a place to stay —so you wouldn't depend too much on your parents— and the opportunity appeared, because there was a guy named Lucas who was looking for a roommate.
At first, you weren't very close, so your conversations were brief, but life was good that way... peaceful, good work, a pretty good house, someone to not feel so alone, completed studies and so on...
But as time went by, you and Lucas began to grow closer. The conversations lasted longer, there was more laughter and smiles, which were now seen, bringing more happiness into your life, and little by little this relationship grew stronger.
Lucas, who was also happy in this life, didn't mind it that much, the only bad thing was that he had a tiring job... And that sometimes made him come home exhausted and end up sleeping in his work clothes, or on the couch, wearing sneakers... And so it goes.
Today, Lucas came home from work, tired as always. He walked into the house, went to the couch and threw himself on it, not even bothering to take off his sneakers—he was too exhausted for that—and it was clear in his entire being.
