Who Brought Whom into Whose Trap?

There is a well-known "Brother Wan" Zhou Beiyou in the northern art circle. He painted Dunhuang Flying Sky on his body, painted and erased it, claiming to be performance art; he wrote love into a hit novel, and he claimed that being honest with women is "playing tricks with ghosts." This philosophy of playing games has made him a legend in the industry. Until he met Lin Shen at an avant-garde art exhibition. Lin Shen holds a PhD in Sociology from Columbia University, specializing in intimate relationships and contemporary emotional models. She is writing a major paper - "Commitment Fear in the Postmodern Context: A Sample of Urban Intellectual Men". Zhou Beiyou, this walking "theoretical practitioner", perfectly meets all her sampling criteria. When an artist is studied for a doctorate in sociology, should he stick to his love principles or follow the trend of gravity? When a researcher is researched by the researcher... Among the physical effects produced by two people, who is the apple and who is gravity?
