Wow. This story by Hannah Cheng of relationship problems between two UH dorm roommates, with its powerfully ambiguous climax, just may be the star of the Dark Paradise: Mysteries in the Land of Aloha anthology. I cared about both of the main characters, giving the ending even more hefty emotional meat (however you choose to interpret the ending).
Go buy the anthology just for this story, if nothing else.
