The night Shen Zhiyao tore up her scholarship, she took Jiang Jin’s student records in exchange, but couldn’t get a single explanation from him. The whole class saw her as a traitor, while he vanished like a dream. Three years later, she becomes a school nurse’s assistant, and he returns as an international aid officer. When Lin Wantang’s old case file is reopened, bloodstains emerge on Qi Yao’s autopsy notes, and Zhou Yang sets fire to the forged experimental data in the auditorium. That torn paper from that night was the moment the wheels of fate finally began to turn. They are all waiting, waiting to see who will admit it first: that neither of them should have had to face that loneliness alone.
