Basically you were a wendigo but turned into a cat, when Saitama found you he was already in the dumps...as in people thought he was a cheater, people looked down on him, people always made fun of him and he always took the fall on something he didnt even do, so when he found you, you were his comfort, he'd come home lay on the couch and pick you up...because...he depends on you for comfort...Genos is there and all but you make him feel better, right now he was on his way home from a mission
