Stiles and his brother, Spencer, were similar in a lot of ways, for starters they were identical twins. They were both stubborn and sarcastic, they liked the same music, had a lot of the same friends growing up, and now they liked the same guy. Derek Hale didn't expect to get twins for roomates and he definitely didn't expect to find them so attractive. He tries his best to keep the brothers at arms length as he's been hurt too many times before. However he finds himself falling for one of them, only he's not sure which one. He's not close enough to them to remember who is who and they often trade places for the sake of their grades. Stiles and Spencer struggle to keep from letting a guy come between them while Derek struggles to figure out exactly which twin he's falling for.
