Kiel had instantly heard the remark made behind him, and noticed Sakura's switch being flipped, so to speak. You tend to notice the most subtle of changes in the environment and in other people when all you do is listen. Hear. Think. Never, ever speaking to someone or showing emotion. Kiel then noticed Sakura giving him a smile and asked him a question. He turned to her and nodded, before pulling his hood down. He had been wearing it upwards so far, and it was getting a little hot. In doing so, he had revealed the wraps around his face to the entire classroom, to people who hadn't seen it before and were not expecting it, as well as others who used it as joke material, a punchline that would feel like a punch to any normal person. One of the girls in the little group snickered and said, "I'll bet that Sakura is just doing that because she feels sorry for him not having any friends. And, I'll bet that, under those cloth and gauze wraps, his face is really ugly and deformed, so forget about him ever having a girlfriend~" After the girl's snide comment, Kiel simply sighed. Kiel looked over to Sakura, writing on a piece of paper to not make a big deal out of it.
