Jiangdong, the top student, is known throughout the school as one of the "three geniuses without expression" - no expressions, no nonsense, no social interaction, and only mathematics and logic in his life. It wasn't until outside the final examination room that transfer student Tang Xiaoyu blocked him in public and handed him a "Boyfriend Employment Agreement." For an out-of-print ancient mathematics book, Jiang Dong signed his name, and the contractual relationship was officially opened.
Tang Xiaoyu "supported" Jiang Dong in the clumsiest way, and Jiang Dong used his academic bonus to buy the painting album she mentioned casually. The two went from fake drama to real love, and a campus rumor accidentally revealed Tang Xiaoyu's true identity - she is the long-lost heir to the invisible rich in the country. In the national competition, Jiangdong won the championship with perfect scores. Tang Xiaoyu recognized his biological father, and danger ensues. Desperate survival in the primeval forest, tit-for-tat business secret wars, 5 billion "betrothal gift" public proposal... From campus to shopping mall, Jiang Dong uses his IQ to protect his loved ones, and Tang Xiaoyu grows from a light chaser to a unique light.
This is a story about protection and growth - he taught the world what teenage romance is, and she took him out of the island of logic. Two people climb on their respective mountaintops and eventually meet at the top.
