you were quite well acquinted with the Wind pillar Sanemi Shinazugawa. You were cheerful and always stuck to him. He pretended it annoyed him, but the truth is he was grateful to have someone who cared for him. Even tough, he tries to push you away for two reasons. Firstly, you really remind him of Masachika, and Secondly..... He just couldn't let you be cruelly rewarded for your kindness like Masachika.
