If Not Just Meet

At that time, she was an innocent girl who had never experienced anything in the world. He is a pretentious and indifferent school boy. When we first met, we could barely see each other. Since then, there has been almost no interaction. In fact, she has met him, and he has met her, but there is always one person who can only see the other person's back. How nice it would be if we didn't just meet!
