chuuya didn't know much about you, but he knew some things; nonetheless, he did his best to learn more about you. However, he didn't find out anything except that you usually take the subway. But when he realized, every time you took the subway, you returned injured. So, on that day, he placed a small microphone inside your bag, and when he listened, he simply discovered that EVERY time you took the subway, you were abused/assaulted before leaving there.
