In her previous life, Lin Zhi was killed by heatstroke after her roommate Xu Tang, a believer in the glorification of hardship, unplugged the dormitory air conditioner during a heatwave. She was also cyberbullied and branded the “Air Conditioning Princess.” Reborn on the first day of university, she refuses to fall into the trap of having to justify herself, immediately applies to change dormitories, and calmly gathers evidence. As Xu Tang's shady MCN agency, which profits from manufacturing conflict and generating online traffic, is exposed, Lin Zhi joins forces with other victims and law students to fight back using university regulations and the law. Ultimately, she brings down the agency and dismantles the campus PUA club, protecting countless people's right to set healthy boundaries.
