Lin Yangyang was concerned that her small intellect would be burdened if she was forced to learn stuff she didn't comprehend. Lin Yangyang prefers to utilize her intellect to retain information relating to her passion, astronomy.
Lin Yangyang's grandmother—Fanxing Lin, frustrated that her only grandchild lacked motivation to study, decided to enroll her in Midnight Nerd. Her grandmother threatened that if Lin Yangyang refused to attend school, she would be a disobedient granddaughter. And the threat succeeded because Lin Yangyang followed her grandmother's wishes.
Lin Yangyang concentrated on her studies as much as possible since she did not want to disappoint her grandma. However, only a few minutes before the start of class, he heard an unexpected sound. Where someone broadcasts on the radio in the middle of the night about a murder case that has never been covered in newspapers or television.
Whenever Lin Yangyang attempted to approach him, he was deafened by loud noises. Until the radio announcer drove him away with a cold tone of voice. Lin Yangyang first tried to seem nonchalant. However, his fascination with that figure was overpowering.
As Lin Yangyang befriended Bai Yilong, a radio announcer, it was revealed that he and his classmates were victims of a fire three years earlier, which was caused by someone who despised his enemy's intellectual grandson, Xiao Xui. Bai Yilong said that Lin Yangyang was the only female who could solve the murder mysteries he would read in the middle of the night.
Until the time came for Lin Yangyang to be wise and solve the murder mystery. He was astonished to learn that his own grandmother, Fanxing Lin, was the cause of the fire that claimed the lives of hundreds at Midnight Nerd. Lin Yangyang, hesitant because he faced a tough option, opted to maintain justice by imprisoning his own grandmother based on the murder proof that Bai Yilong consistently disseminated.
After five years, Lin Yangyang has established herself as an evening radio personality who discusses astronomy. He became a radio broadcaster because he missed the ghost who had penetrated his heart. On Halloween night, he encountered a human-like figure resembling Bai Yilong.
