Mo Yuxing works part-time at a milk tea shop called "Twilight Tea", and his life is ordinary. Until Jiang Ningwei joined the company, she was quiet, cool, talked little, and always liked to be in a daze from time to time. She carries a black notebook with her and always likes to write down content in her spare time. Mo Yuxing thought she was just an introverted and indifferent new colleague who liked to record life. It wasn't until Jiang Ningwei transferred to another school and became a classmate and appeared more and more frequently in his life that he realized that the notebook contained Jiang Ningwei's long-term paranoia and madness.
