On the first day of the school year at Xinglan University, Su Nianxing, a road-crazy sweet girl, ran into the arms of Lu Shiyan, the master of the mathematics department. Not only did she knock over his formula notebook, but she also rubbed ink on her own notebook full of star illustrations. This mistake became the starting point of their fate.
Her classmate, math tutoring partner, and regular partner in the library, Lu Shiyan, the flower of the high mountain, is externally a master of modeling with meticulous logic, but internally, she is a jealous boyfriend who can write love letters using the "heart-shaped formula" and stay up late to help her repair illustration files; Su Nianxing, a soft-spoken school committee member, appears to be a good girl with perfect scores in classical Chinese, but secretly is the hidden illustrator "Xingluo" with millions of fans, and the silhouette of a certain boy in a white shirt is hidden under the brush.
The support in the military training field, the bookmarks on New Year's Eve, the advertisements at the school anniversary party, and the side by side on the competition field. In their youth, there was the exclusive feeding of sweet and sour pork ribs, the two-way running of illustrations and formulas, the divine assists of the best friend group, and the funny troubles of the small group. There are no bloody misunderstandings, only the sweetness of flowing water; there is no shocking sadomasochism, only the warmth of growing together.
From the tree-lined avenues of Xinglan University to the aurora in Iceland, from campus lovers to entrepreneurial partners, and then to entering the marriage hall hand in hand, they used their four years of youth to prove: The best love is the science and romance of you understanding me, and the gentleness of liberal arts I protect you.
Just like what is written on the title page of Lu Shiyan's treasured notebook: "After meeting Su Nianxing, all the unsolvable formulas have the sweetest answers."
