I liked the first story but the other two just left me with a "huh?".

this could be totally wrong:
but in the second story, i got the vibe that the main character was responsible for the accidents occurring in front of his apartment complex; because he is so good-looking he gets away with a lot of things.
(the guy that was found in critical condition at the end might be the guy that the main character slept with?)

That's also what I was assuming, but everything was just so vague that I couldn't really make a conclusion.
