Male, a professor from Jingbei University who teaches math at the Chuying Sunshine cram school. In Jiang Zhiyu's past life, he was her clingy follower who always ranked second behind her at Beijing North High. He went abroad after high school in her past life but is now teaching in China. He is described as the perpetual runner-up and academic top dog. He seems to have lingering feelings for the Jiang Zhiyu from his memories.
