Synopsis
Su Wan is enrolling her daughter in school when the process stalls halfway. Zhang Cheng, the principal of the private school, develops ill intentions during a meeting. He first sexually harasses her verbally, then lays out his terms of exchange. Su Wan is deeply repulsed, but she has her family to think of, so she doesn't tear into him on the spot and can only appear to go along for now. She does not give up her bottom line, and nothing improper happens between them. Later, to gather a complete set of evidence, she is manipulated by the principal again and again.
