Wufei hummed in response, simply echoing Isamu's words with affirmation. They were the same. Even if they couldn't say exactly what this was between them, they both felt it and that counted for far enough. He sighed, squeezing Isamu's hands before finally pulling them away. The touch of their fingers trailing together made him want to grasp them together again, but he resisted as logic won out. "You should go then. I'll still be here tomorrow after all. It is a son's duty not to make his parent's worry. I would hate to be something that stood in the way of that." Even if he wanted Isamu to stay. Even if he wanted far more than he could ever have. For now, he knew it was best to let go.
