There was a detail that stuck out in the story told by Zhang Ju. A girl had confessed to her senior on his birthday but ended up being rejected. After that, the senior had joined his roommates to celebrate his birthday at the karaoke. When Chen Ge first met Zhang Ju, the latter had once said that his face had been scarred at a fire that started at a karaoke center. Initially, Chen Ge did not tie the two together, but now, Zhang Ju was acting too abnormally, so this thought surfaced in his mind.
All the club members' memories during the summer holiday were blurry; in other words, someone had tampered with that period of their memories, and thus, what they recalled could not be trusted fully. Zhang Ju was very familiar with the school and knew the details between the senior and the girl very well. Other than that, his face had been injured in a fire at the karaoke center, which matched the story of the senior a bit too perfectly.
