Before the Stardust Fades Away

Lin Wan is a senior idol nerd and a member of the campus mystery club. In reality, she silently follows the seemingly flawless top idol Shen Xing, the leader of the phenomenal idol group "X Star". An accidental elevator accident allowed Lin Wan to travel back to three years ago - just before Shen Xing was about to debut, but encountered a major scandal "Live Broadcasting Gate" incident. That incident caused Shen Xing to almost be hidden by the company. Although he finally forced his debut, the rumors of being a "barmaid" and "selling her body" have always followed, and there are still people anonymously smearing him on forums to this day. After Lin Wan returned to the past, she discovered that the "Live Broadcast Gate" was not a simple revenge by anti-fans, but a carefully planned murder attempt - someone intended to poison Shen Xing during the live broadcast, but Shen Xing accidentally escaped, leaving only the illusion of "accompaniment". The real murderer has been hiding in the dark. Lin Wan decided to use this opportunity to travel back and forth to investigate the truth three years ago while protecting Shen Xing. However, every small change in history will trigger a butterfly effect in reality - she found that when she successfully changed an event, the "now" of reality would also be distorted. She must integrate into the time and space three years ago without exposing herself, while luring the real murderer to reveal himself.
