Lin Zhixia mustered up the courage to confess to Shen Mobai, the school sweetheart she had a crush on for two years, but accidentally tore off the confession he had posted on the wall. Behind that piece of paper, there was actually a clue to the access sign leading to the abandoned warehouse. In order to make up for their mistakes, Lin Zhixia and Shen Mobai were forced to cooperate in the investigation, but they attracted the "enthusiastic help" of senior Song Qinghe and the "goodwill" transaction of Uncle Qian of the canteen. As the secret of the token emerged, she discovered that the confession had already been involved in a conspiracy, and everyone around her had their own purposes in helping. Lin Zhixia used wisdom and courage to tear apart the lies and protect her original intention.
