The starting point of the story is a identity mistake: Orion, a rapper, is searching for a female model for a video. Among the stock of photos the agency sent him he picks up Darien, a dark haired beauty with long straight hair. In the rush he doesn't understand to his personal assistant who are trying to tell him that Darien is a boy not a girl. When Darien receives the call from his agent he wonders why a rapper, a category that usually is not exactly LGBT friendly, wants him for his video. The day after Darien wents to the shot and realizes immediately that Orion believes him a girl. He tries to leave without further problems, but Orion stops him, and not for doing the shot.
While Darien's character and his motivations are quite explained, it's not the same for Orion. Darien is a model, and as all the models maybe he is also a little vain. He knows that he looks like a girl, but he likes himself; he doesn't want to change his imagine most of all since he loves his image. And in his job, it's not a problem, so he has never had to face that problem. When he meets Orion, he likes him as a man, above all since Orion is so manly and strong, a nice and big contrast to himself. Since Darien is not ashamed of being a boy, he never once thinks to continue with the mistaken, he wants only to go and don't have trouble.
As I said, I didn't frame so much Orion. What it is clear is that he likes Darien, both when he thought him a girl than now that he knows that he is a boy. What it's not clear is if Orion was bi-curious even before; I believe not, I think he maybe had some interest but never acted upon it, and Darien, with his androgynous look is a perfect point to start exploring. On this perspective, I don't know if this will be forever love, but for sure it's a nice romp.
