There were some contradictions along the way as both characters either threw themselves at each other or ran in opposite directions. I can argue that Josh was somewhat motivated, having willingly initiated sexual contact with another man. He was confused as to what it meant and how it affected him, since his only other reference was an orgy where he was not emotionally invested. And now, he was spending time with a man to which he feels attracted.
Matt, on the other hand, was all over Josh one moment and playing it cool and aloof the next. Though towards the end, he did seem to make up his mind and play the understanding gay man.
It wasn't a very heavy plot, nor were the characters complicated. But sometimes, sweet and short will do the trick.
