Black Box Star Observation Logs

At Yunli Academy, there once was a five-member detective club. But now, only four member files remain. A name erased, images that cannot be viewed, a fifth person who should not appear in the group photo, and a black box containing the whole truth that no one can open: every clue proves that she once existed. Strangely, no one has forgotten her. To search for the missing Yuqian Cha, Mo Zhu, Chun Xia, Dolly, and Yu Weiba have restarted an investigation that had been closed. After Mo Zhu temporarily leaves, Youzhui joins as a stand-in, while Yu Weiba becomes a roving member outside the official roster. This seemingly incomplete new arrangement has just one purpose: to follow the traces she left behind and find the real "Black Box Star." Yet as the investigation continues, they gradually discover that perhaps more than one person's file has been deleted. The Yuqian Cha they remember may not be the real Yuqian Cha, either. And the Black Box Star that still operates today seems never to have belonged to the real Black Box Star. This is an observation record about a missing person. It is also a long missing-person notice, written for her by those who refuse to forget.
