"Hi, long time no see... Do you still remember 'go in the direction of the light and don't look back'?" A reunion greeting awakened the memories of Deng Yanyan and Xiao Xiao's eight-year-old youth. In high school, Deng Yanyan, a scumbag in mathematics, and Xiao Xiao, a god of study, got to know each other because of the aid program. The burnt cookies and crooked formula love letters concealed a tender heart, but they were scrawled goodbye when Xiao Xiao emigrated unexpectedly.
Eight years later, Xiao Xiao returned to China to take over a construction project, and unexpectedly reunited with Deng Yanyan, who opened a dessert shop, for cooperation. The former academic god and the academic scumbag started a frantic collaboration, using trigonometric functions to fight each other, using chemical principles to adjust desserts, and with the help of resentful partners, arrogant rivals, and arrogant best friends, they staged a hilarious and heart-warming polyamorous stew.
From campus to the workplace, they use their high school knowledge to build their careers. Dessert shop chain and construction dreams go hand in hand; from lovers to husband and wife, the sweet pet of the god of learning runs through their daily life. After marriage, they unlock a new copy of parenting - a pair of children with science genes, turning raising children into a "formal parenting competition".
The whole process is dense with memes and has an over-the-top sugar content. It contains both the shy memories of youth, the inspirational feeling of young people's hard work, and the daily fireworks and warmth of family. It writes a two-way journey of "walking in the direction of light, from youth to old age".
