In order to avoid a business marriage arranged by her family, Su Wanqing, a scheming beauty with hundreds of billions of assets, disguised herself as a "poor transfer student" and sneaked into the most chaotic "Xinghuo Vocational and Technical College" in the country. She planned to find a passerby with a "clean background" to fake a marriage and get through. By some strange combination of circumstances, she sets her sights on Lu Xingyan, the famous "idiot school boy" in the school. He seems to have strong limbs and a simple mind. He can pronounce "Advanced Mathematics" as lines from "Peppa Pig" in class, and can run 100 meters at the sports meeting to buy sausages at the vegetable market next door. In fact, he is a hidden top hacker and heir to a mysterious consortium. He is investigating the school director's corruption case as a "scumbag" undercover.
Su Wanqing's "fake marriage plan" was full of troubles as soon as it was launched: she pretended to fall and bumped into porcelain but fell into a mud puddle, designed a hero to save a beauty, but Lu Xingyan mistakenly thought a stray cat was a murderer and chased him three streets. Lu Xingyan regarded Su Wanqing's abnormal behavior as "a strange way for poor students to eagerly integrate into the group". While cooperating with her "performance", he secretly collected "dirty information" about her, but as they got along with her, he gradually became attracted to her childishness and contrasting cuteness under her sinister appearance.
The two were bound together in a busy campus life: together they helped the cafeteria aunt catch the wild boar that stole food, recovered the lost square dance partner (a parrot) for the dormitory supervisor, accidentally broke into the international hacker competition and won the championship, and even changed the wedding dress into a Taekwondo uniform at the family marriage banquet to fight. As the school director corruption case deepens, the true identities of the two people are exposed one after another, and the original "mutual use" turns into a two-way rush...
