Xie Ye, the most arrogant plutocratic prince of Shengjia High School, woke up and turned into Lin Mian, the poorest student at the bottom of the school? What's even more outrageous is that the usually submissive "doormat" is now pressing against his body, with eyes even more fierce than his! On a thunderstorm night, the fate of the two people was misaligned. There is only one rule: swap in the morning and return at sunset. As a result, the craziest "tyrant" in the school was forced to live in a leaky rental house, experiencing poverty where he could not even afford breakfast, and had to endure bullying for "himself"; while the "transparent man" at the bottom of the food chain unexpectedly gained the power and force of the top wealthy families, and began to clumsily fight back against those former abusers. During the day, they are each other's perfect disguises; at night, they face their own turmoil alone. In order to fight against the control freak father and the cruel campus rules, the two were forced to form an alliance: "Since we have exchanged, use my body to fight a bloody path for me!"
