Seth was a little surprised when she said she needed to think about it. It was okay, he had laid enough out there so that it stuck in her mind. It would fester and grow and make her want it...want it more than she wanted everything. Time was exactly what was needed for his seduction to work. So her "needing to think" was the perfect course of action. He kept up the concerned look so she would still think he was being genuine. "I understand Fi, it's a lot to take in and I'm sorry I sprung it on you so suddenly. I hope it's not just a lingering crush, I hope you can view me as just a normal guy, not the man who used to be your teacher."
He saw that her answer to him was bothering her. She'd think it over and he'd keep up the "I love you and want something with you" act whenever she was around until she finally crumbled. He knew she'd crumble eventually, girls like her always did. "Well, I think it's best I made it back to my post," he leaned in and gave her a gentle kiss on the forehead, "make sure to lock up before you leave." With that he passed her and made his way back to the theater. Once he was certain he was far enough away from her he let that wicked smile come to his face.
