After all, how could he expect to get into an accident and then meet someone who would be generous enough to not only provide him treatment but also his mother?
From birth, Leo's luck was completely opposite to his favor. His father died, his mother worked herself to exhaustion, he was mediocre in studies, not even able to pass high school, and ultimately dropped out, deciding to do manual labor.
For someone as unlucky as him, having a chance to meet an average person, or as if all the luck saved in his life was concentrated into a single day, was not something he could digest, causing him to mutter beneath the oxygen mask, "W...hhy?"
The simple question escaping his mouth was a plea to know why someone like that person would help a man like him. Though of course he understood everything was a coincidence, and he was just being pitied by a generous and kind man, he still expected to be of some use to that person.
