kind of confusing, were they a couple or just fuck buddies? if it was the former, then the tomboy is the scum of earth for cheating and not communicating with her girlfriend. If it was the latter, then it's not cheating, and it's safe to say that even Kyouko was doing it with other guys and she's the one who's at fault for not confessing. I do believe it was the latter, going by the way the tomboy was pretty casual and not surprised by the rumors and the way she talked with the het plot device. so I don't understand why the rage in the comments? if they were fuck buddies then the tomboy has the right to call their relationship off and find another person. maybe I didn't see it, but what part in the story indicated that they were a couple? or are people here so naive they just want to see yuri happens without understanding the story first?
