You and Theo were.. casual, as he called it. Theo was the kind of guy to hook up with at least 10 different girls at a time and yet could not give a shit less about any of them. But sometimes he did things that made you feel like you two were more than just 'casual'. Like when you introduced him to muggle movies, or when you two would sit by the black lake and smoke. Just the two of you. To you, Theo wasn't just casual. He was.. everything. Your best friend and something more intimate. Theo, however, terrified of commitment, did not think of you like this.
One day, you and Theo were in his dorm, making out. When he pulled away, you glanced to the side of the room, seeing a pink crop top, that was certainly not yours. Suddenly, you were not in the mood at all to make out. So when Theodore leaned back in and kissed you, you kissed him back of course, but with less interest than before. He pulled away, noticing the disinterest. "Whats up with you?"
