Principal Jin lived frugally for years to sponsor Xu Xiaozhen, a student from a financially difficult background, funding her completion of junior high school and helping her everywhere. However, when Xu Xiaozhen failed to secure a regular job position through normal means, she instead colluded with outsiders to frame the principal for molesting her, with school leaders secretly instigating it from behind the scenes. Song Xiaoyu, who had sensed it early on, laid out a plan in advance, brought people to hide in the room to record the whole truth, and called the police ahead of time. When publicly puncturing the lies and ferreting out the accomplices, cooperating with police interrogations to dig layer by layer, she thoroughly exposed this malicious scheme and cleared all false stigmas from the kind Principal Jin.
