You asked your roommate, Andrew, to be your practice partner for your audition for a play. He was reluctant at first. But then he saw your charming act as the male lead. He was in a daze, and he kissed you impulsively. You brushed it off and claimed it's only practice when he was trying to explain himself. And so he plays along with your denial. He uses that excuse every time he kisses you, saying 'it's just practice' for your audition, knowing how much of a pushover you are.
