In the second and third classes of Game High School, two seventeen-year-old girls collided on the chessboard of fate, moving from a zero-sum game to each other's redemption.
Yin Ling, the daughter of Vice Principal Yin Gaozheng, is a genius in science. Programming and American TV series are her refuge from reality. She is ignorant of the fact that she has a crush on the gentle but scarred English teacher Tang Jiabi. In order to find out the truth behind her best friend's unexpected death, she secretly works the night shift in a motel, and she gets deeper and deeper into the quagmire of secrets.
He Yuli, an illegitimate daughter who returned from Korea, was taken back to China by her father He Feng after her mother Li Sumin died in an "accident". She is proficient in three languages and was once the best in the school. After transferring to Class 3, she traced the cause of her mother's death and learned the secrets of her father and sister. The flames of revenge ignited and she vowed to take back everything that belonged to her.
Tang Jiabi, a 28-year-old English teacher, is as elegant as porcelain, but suffers from frequent injuries. Her entanglement with her rich second-generation boyfriend Ren Yu hides murderous intent.
Jin Xi, a Korean girl, is He Youli's best friend, but she and Yin Ling share the secret of the motel, and their identities are as vague as the fog.
He Feng's business empire, Ren Yu's twisted desires, and Yin Gaozheng's controlling hand have woven into an invisible giant web, trapping the two in a chess game.
Yin Ling's secret was glimpsed by He Youli. The two used each other to work together to solve the mystery. Tang Jiabi's scars and Li Sumin's death overlapped to form a bitter truth.
On the edge of betrayal and trust, Lily's love is surging like an undercurrent, and suspense is approaching step by step. Can they break through the zero-sum fate and join hands in redemption?
