Mirror Testimony

They thought that time would bury everything. Until the first deceased appears. Seven unrelated successful people were murdered one after another. At the scene of each murder, a note revealing the past was left. There were no witnesses, no motive, and no evidence to prove the identity of the murderer. As the investigation deepens, an important incident that has been sealed for many years once again comes into public view. Some people say that it is just youthful ignorance; some people say that the victim should have let go long ago. But there are always people who don't want to forget. The truth is getting closer, yet further and further away. Because the real danger is not the murderer, but the past that has never been tried.
