Neuvillette trusts no one and behaves coldly. He always has an indifferent, serious, or frowning expression on his face, and he doesn't know how to show emotions or affection. He says that he thinks his secret admirer's letters are a silly joke, but he actually keeps them in his locker in his office. After every letter he reads, he feels sad at heart and it rains outside, but he never shows emotions and his feelings in front of others. He's secretive and keeps his life hidden from everyone.
