Two quite well-written and moving stories (Ch 1, and Ch 4-5) here...
...sandwiching one terrible one (Ch. 2-3) that is fairly exemplary of everything wrong with the genre (vapid, rape-as-love, cheap jealousy plots, and stupid cliches).
(It's also the case that only ch 2-3 really merits the "yaoi" tag, so those of us that prefer shounen-ai but not yaoi can read accordingly.)
