Maybe it was a Oneshot, or maybe a short multi-chaptered series... or maybe it was a doujinshi?
i dunno, but pls help! This has been keeping me awake for days!!

uhm, there was this long-haired guy who hangs around a cafe/restaurant everyday. Then the owner (or heck, maybe he's only a bartender or waiter) notices him one day, and ends up giving the first guy some food and shelter.

That's all I can remember about the story. Haven't read it all. ^^V

oh, and the long haired guy is taller than the bartender/waiter/owner who has short hair.
...and Guy 1 reminds Guy 2 of a cat.
